SUMMARY:Close encounters of the primordial kind: A new observable for primordial black holes as dark matter (Tung Tran - Stanford University\, USA)
DESCRIPTION:Speaker: Tung Tran (Stanford University\, USA) \nHost: Dr. Nguyen Trong Hien (NASA\, USA) \nAbstract: Primordial black holes (PBHs) remain a viable dark matter candidate in the asteroid-mass range. We point out that\, in this scenario\, the PBH abundance would be large enough for at least one object to cross through the inner Solar System per decade. Since Solar System ephemerides are modeled and measured to extremely high precision\, such close encounters could produce detectable perturbations to orbital trajectories with characteristic features. We evaluate this possibility with a suite of simple Solar System simulations\, and we argue that the abundance of asteroid-mass PBHs can plausibly be probed by existing and near-future data.

SUMMARY:From interferometry to cosmology with fast radio bursts (Dr. Calvin Leung - UC Berkeley\, USA)
DESCRIPTION:Speaker: Dr. Calvin Leung (UC Berkeley\, USA)\nHost: Dr. Nguyen Trong Hien (NASA\, USA)\nTime: February 13 @ 2:00 pm UTC+7 (February 12 @ 11:00 pm PST) \nAbstract: The current generation of cosmological surveys like LSST\, Euclid\, DESI\, and CMB-S4 will be limited by our understanding of galaxy formation\, AGN feedback\, and the diffuse\, baryonic universe. Meanwhile\, fast radio bursts (FRBs) are millisecond duration radio transients which\, despite their mysterious origin\, are sensitive probes of the diffuse\, ionized gas in and around galaxies. The race is on\, fueled by Moore’s Law and the GPU/AI revolution\, to build instruments capable of detecting these mysterious transients and pinpointing them with sufficient angular resolution to understand their origin and unlock their cosmological potential. I will outline my work transforming the Canadian Hydrogen Intensity Mapping Experiment into the world’s most powerful FRB detection and localization machine using low-frequency very long baseline interferometry (VLBI): a technique\, abandoned decades ago\, which we have revived for FRB localization. I will also show how FRBs can be used to probe the unseen universe on all scales: from Jupiter-mass primordial black holes\, to the ionized interstellar and circumgalactic media\, to diffuse baryons on cosmological length scales relevant for weak lensing. \nJoin Zoom Meeting\nhttps://zoom.us/j/94274604480?pwd=Mi4HlfhBYX4mpPPGd4f2MgsrnMnquF.1 \nMeeting ID: 942 7460 4480\nPasscode: 602372

SUMMARY:Supermassive Black Holes as Cosmic Architects: Insights and Future Directions (Dr. Nguyen Duc Dieu  - Lyon University\, France)
DESCRIPTION:Speaker: Dr. Nguyen Duc Dieu (Lyon University)\n\nHost: Dr. Nguyen Thi Phuong (VNSC & SAGI)\nTime: 2:30 PM (Vietnam time\, UTC+7)\n\n\nAbstract:Supermassive black holes (SMBHs)\, residing at the centers of galaxies\, play a pivotal role in shaping the formation\, evolution\, and structure of their host galaxies. My research focuses on unraveling the dynamic interplay between SMBHs and their environments\, particularly through precise measurements of black hole masses and the feedback processes that regulate star formation and galaxy growth. Using advanced observational facilities\, such as Keck\, VLT\, ALMA\, HST\, JWT\, and cutting-edge instruments like ELT/HARMONI\, I aim to address key challenges in the field\, including the detection of elusive intermediate-mass black holes and understanding the mechanisms of black hole formation\, growth\, and feedback.\nThis talk will highlight my discoveries in SMBH research\, including refined mass measurements in galaxies below the Milky Way scale\, and the transformative potential of next-generation observatories in probing SMBH-host galaxy co-evolution. I will also discuss how these studies inform broader questions about cosmic structure formation and the future of high-resolution\, multi-wavelength observations in extragalactic astronomy. This journey from local galaxies to the high-redshift universe offers a roadmap for exploring the next frontiers of observational astrophysics.\n\n\n(download presentation slides)\n\n\nZoom link:\nhttps://zoom.us/j/97208434236?pwd=ChCAhIWXVlrYXymSakLDqCbc7qWk5D.1\nMeeting ID: 972 0843 4236\nPasscode: 795349

SUMMARY:Seeing stars during the day: The Huntsman Telescope and the development of daytime optical astronomy and space domain awareness (Sarah Caddy - Melbourne Space Laboratory\, Australia)
DESCRIPTION:Speaker: Dr. Sarah Caddy (Melbourne Space Laboratory)\n\nHost: Dr. Nguyen Trong Hien (NASA)\n\nTime: 2:30 PM (Vietnam time\, UTC+7)\n\n\nAbstract: Traditionally\, ground based optical astronomy has been restricted to night time observations due to the brightness of the daytime sky background. The advancement of commercial off the shelf (COTS) CMOS detectors (usually used in smart phone cameras) has come so far in recent years that they are now widely used for astronomical observations. They also have the benefit of being able to take millisecond duration exposures\, and hundreds of frames per second. Leveraging this technology\, we demonstrate successful observations of bright and variable stars at all times of the day with the Huntsman Telescope. In addition\, we demonstrate ~10% daytime photometry\, and a surprising discovery of the brightness of artificial satellites during the day which we demonstrate to be attributed to Earthshine. I will discuss these recent developments made with the Huntsman Telescope\, and the implications that these findings have for space domain awareness performed with small\, autonomous COTS telescope systems in an effort to protect assets in space.\n\nJoin Zoom Meeting\nhttps://zoom.us/j/91797517733?pwd=ygpMQFdp2CwcVJVp1ajkbXflvCE1SL.1\nMeeting ID: 917 9751 7733\nPasscode: 252882

SUMMARY:Gas and Dust Properties in Protoplanetary Disks at mm/sub-mm wavelengths (Dr. Nguyen Thi Phuong - DAP/VNSC & SAGI/IFIRSE\, Vietnam)
DESCRIPTION:Speaker: Dr. Nguyen Thi Phuong (DAP/VNSC & SAGI/IFIRSE\, Vietnam) \nHost: Dr. Thiem Hoang (KASI & UST\, South Korea) \nTime: 2:30 PM (Vietnam time\, UTC+7) \nAbstract: Protoplanetary disks are the birthplaces of planets\, consisting of gas and dust that evolve through complex physical and chemical processes. Understanding the properties of gas and dust within these disks is essential for unraveling the initial conditions of planet formation. Millimeter and submillimeter wavelengths provide a powerful window into the gas and dust properties of protoplanetary disks\, offering crucial insights into the early stages of planet formation.\nIn this talk\, I will present recent studies characterizing the physical and chemical properties of a couple of prototype protoplanetary disks using observations from ALMA and NOEMA. I will discuss the gas and dust morphology\, grain growth\, gas kinematics\, and chemical composition in environments that favor the formation of planets. \n(download presentation slides) \nZoom link:\nhttps://zoom.us/j/94590451235?pwd=ILTGhblOhNQOJbR2AcnXcCDJzBAsBB.1 \nMeeting ID: 945 9045 1235\nPasscode: 651623

SUMMARY:Possible impact of environment on star formation in the Outer Galaxy (Dr. Ngân Lê\, SAGI/IFIRSE\, QuiNhon\, Vietnam)
DESCRIPTION:Speaker: Dr. Ngân Lê (SAGI/IFIRSE\, ICISE\, Vietnam)\nHost: Dr. Nguyen Trong Hien (NASA)\nAbstract: Star formation is ubiquitous in the Galaxy\, but the physical and\nchemical conditions in star-forming sites might differ due to the\nenvironment. For example\, due to the negative metallicity gradient\,\nabundances of molecules and dust are expected to decrease with the\ndistance from the Galactic Center\, and subsequently influence the\ncooling budget and the star formation efficiency. Magnetic fields\n(B-fields) are also believed to play an important role in star\nformation processes and in the evolution of the molecular cloud.\nIn this talk I will present results in investigating the role of\nmetallicity and B-fields in molecular clouds where new stars are born\nin our Galaxy. I will present results of infrared studies where we\ncharacterized the gas accretion onto young stellar objects and the gas\ncooling in embedded cluster in the Canis Major region at l~224°\n(CMa-l224) in the outer Galaxy\, using data from NASA/IRTF and\nSOFIA/FIFI-LS\, respectively. I will also present results concerning\nroles of B-fields and stellar radiation from a nearby high-mass star\nin regulating the star formation and shaping the nearby molecular\ncloud Rho Ophiuchus-A.  \n(download presentation slides) \nVenue: Room 804\, A6 Building\, 18 Hoang Quoc Viet\, Nghia Do\, Cau Giay\, Ha Noi\nZoom link:\nhttps://zoom.us/j/95216074173?pwd=OL4Yu1EsObJnZWfvFRIPpdPCYTncIe.1\nMeeting ID: 952 1607 4173\nPassword: 491383

SUMMARY:Promoting astrophysics in Viet Nam: an effort of over two decades (Prof. Pierre Dariulat - VNSC\, Hanoi\, Vietnam)
DESCRIPTION:Speaker: Prof. Pierre Dariulat (VNSC\, Hanoi\, Vietnam).  \nAbstract: Between 2001 and 2014 the Institute for Nuclear Science and Technology in Ha Noi helped us with starting a new research effort by welcoming us in its premises. We started with research on cosmic rays\, first on our own\, then within the International Pierre Auger collaboration\, becoming the Vietnam Auger Training Laboratory (VATLY). We then prepared ourselves to switch to stellar astrophysics by doing research of our own using a small radio telescope and starting a collaboration with astronomers in France. Since 2015 we became the Department of Astrophysics of the Vietnam National Space Center\, an institute of the Vietnam Academy of Science and Technology\, where we do research in stellar physics\, both protostars and evolved stars\, and on the early Universe; and both on our own and in collaboration with astronomers in France and in Asia. \nI shall recall the main episodes of this adventure and review both what we succeeded and what we failed to accomplish\, trying to learn lessons from this experience and identify the main directions along which we hope to progress.  \nThe public lecture will be given in the framework of the 8th Vietnam School of Astrophysics (8th VSOA).  \nVenue: ExploraScience Quy Nhon.

SUMMARY:Dust Polarization and Radiative Torque Paradigm: observations meet theories (Dr. Le Ngoc Tram - MPIfR Bonn\, Germany)
DESCRIPTION:Speaker: Dr. Le Ngoc Tram (MPIfR Bonn)\, Host: Dr. Thiem Hoang (KASI & UST\, South Korea) \nAbstract: Absorption polarization from interstellar dust was discovered in the 50s\, and emission polarization was first reported in the 80s. Many more dust polarization observations with higher sensitivity and resolution have been deployed in the last decades. Theories have also been proposed and updated to understand observations comprehensively. The most popular theory is the Radiative Torque Alignment (RAT-A)\, which relies on the interaction between an incident anisotropic radiation field and an irregular-shaped dust grain. Recently\, suprathermal dust rotation by radiative torques has been found to induce rotational fragmentation of the largest grains. This new non-thermal disruption is called Radiative Torque Disruption (RAT-D). The combination of the RAT-A theory and the RAT-D mechanism is known as the RAT paradigm. The vast majority of predictions made by the RAT paradigm have been tested from observations. In this talk\, I review the fundamentals of the RAT paradigm and the application for single and multiple-wavelength observations\, both from dust absorption and emission polarization. \n(download presentation slides)

SUMMARY:New insights on the properties of the first generation of galaxies from the JWST (Dr. Nicolas Laporte - LAM\, France)
DESCRIPTION:Speaker: Dr. Nicolas Laporte (LAM)\, Host: Dr. Pham Tuan Anh (VNSC) \nAbstract: One of the most exciting challenges in modern extragalactic astronomy is to understand how the first galaxies emerged from a dark Universe and how their physical properties evolved. Significant advances have been made in the last decade\, thanks to the introduction of new telescopes and instruments such as ALMA\, MOSFIRE\, MUSE\, and JWST\, along with deep and wide surveys like Frontier Fields\, UltraVISTA\, and CANDELS. In 10 years\, the observational frontiers of the Universe have expanded from z~9(2012) to z~17 (2023). The number of spectroscopically confirmed galaxies with z>6 has surged from a dozen (2012) to several hundred (2024)\, including around a dozen at z>9! By combining data obtained from multiple instruments across a broad range of wavelengths\, it is now possible to determine key physical properties of individual high-z galaxies\, such as their age\, escape fraction\, size\, radiation field\, and metallicity. Through the study of the entire population of very high-redshift galaxies\, we can also infer when the first generation of galaxies formed during the early Universe (known as the Cosmic Dawn) and their contribution to the Epoch of Reionisation. In this presentation\, I will describe some of the latest findings regarding the physical properties of the first generation of galaxies.  \n(download presentation slides)

SUMMARY:The role of hub-filament systems in the formation of star-clusters with low- to high-mass stars
DESCRIPTION:Speaker: Dr. Doris Arzoumanian (NAOJ)\, Host: Dr. Pham Ngoc Diep (VNSC) \nAbstract: Observations reveal the organization of the interstellar medium into filament networks. In molecular clouds\, the densest filaments are identified as the precise birthplaces of solar-mass stars\, while high-mass stars form in the hubs where the filaments merge. To understand the formation process of star-clusters\, it is thus essential to describe the formation and evolution of filaments and hubs and their fragmentation into pre-stellar cores\, the progenitor of stars. I will present theoretical and observational studies indicating the formation of filamentary molecular clouds at the edge of expanding bubbles. I will then show observational results suggesting the role of filament coalescence and hub-filament systems in the formation process of stars from low to high masses. I will also discuss our new study proposing the formation of the Sun along a dense molecular filament. We suggest that the host filament may play an important role in shielding the young solar system from a nearby supernova explosion while intercepting the required amount of supernova ejecta to explain the observations of primitive material found in meteorites.

SUMMARY:Integral Field Spectroscopy in lensing cluster fields - recent results and prospects of the BlueMUSE instrument
DESCRIPTION:Speaker: Johan Richard (Lyon University)\nHost: Dr. Pham Tuan Anh  (VNSC) \nTime: 2 PM (Vietnam time\, UTC+7) \nThe advent of panoramic integral field spectrographs\, such as the MUSE (Multi Unit Spectroscopic Explorer) instrument on the Very Large Telescope\, has offered the new capability to obtain efficient and massive spectroscopy in very crowded fields. When combined with massive clusters serving as gravitational telescopes\, it has truly improved the modelling of cluster mass distribution and extended our view of distant background galaxies. I will present some of the main results obtained with MUSE on a large sample of galaxy clusters\, focusing in particular on the lensed Lyman-alpha emitters and their circumgalactic medium. The excellent performance of MUSE calls for the development of additional panoramic integral field spectrographs. I will describe the current development of BlueMUSE\, a blue-optimised\, medium spectral resolution\, panoramic integral field spectrograph under development for the Very Large Telescope. With an optimised transmission down to 350 nm\, a large FoV (at least 1 arcmin2) and a higher spectral resolution (λ/Δλ ~ 4000) compared to its predecessor\, BlueMUSE will open up a new range of galactic and extragalactic science cases allowed by its specific capabilities. Among these science cases I will focus on the prospects of BlueMUSE in lensing cluster fields.

SUMMARY:How do dense cores form in molecular clouds? (Fumitaka Nakamura\, NAOJ\, Japan)
DESCRIPTION:Stars form from dense cores in molecular clouds. Therefore\, it is crucial to understand how the cores form in molecular clouds. We recently analyzed the Herschel data of nearby molecular clouds\, focusing on the core mass and separation\, and we found that they are smaller than the values expected from  Jeans fragmentation and filament fragmentation. We suggest that turbulent fragmentation may be the primary process to form cores.

SUMMARY:Seminar by Silvia Zhang (Caltech)\, on Wed\, 22/3\, from 9 am (Ha Noi time)
DESCRIPTION:Speaker: Silvia Zhang (Caltech\, USA) \nTitle: Development and Deployment of the BICEP Array BA2 150 GHz receiver  \nAbstract: \nThe BICEP/Keck Collaboration is currently leading the quest to the highest sensitivity measurements of the polarized CMB with a series of cryogenic telescopes\, of which BICEP Array is the latest Stage-3 upgrade with a total of 30k+ detectors. The instrument is comprised of 4 receivers at different frequencies spanning 30 to 270 GHz\, with the low-frequency 30/40 GHz one already deployed to the South Pole Station in late 2019. The full complement of receivers is forecasted to set the most stringent constraints on the cosmological inflationary model and the overarching “small-aperture telescope” concept is already being used as the reference for further Stage-4 experiment design.  In this talk I will present the science goal of BICEP array\, and the development and deployment of the BICEP Array 150 GHz BA2 experiment\, spanning module development\, readout design\, cryostat testing\, detector characterization\, and finally deployment and installation at the South Pole during the 2022-2023 Antarctic season. I will also go into the non-technical aspects of both bringing an experiment down the South Pole\,  and life in general in Antarctica. \n  \nZoom Link: \nhttps://zoom.us/j/3199318714?pwd=ZlV3VCsraHpYeGpIRlYwY2hEaU5Gdz09 \n\nMeeting ID: 319 931 8714\nPasscode: sagi2022

SUMMARY:Seminar by Nguyễn Hạnh Chi (Caltech)
DESCRIPTION:Title: The Cosmic Infrared Background ExpeRiment 2 (CIBER-2): A Near-Infrared Sounding Rocket Payload to Study Large-Scale Structure Formation \nAbstract: \nThe emission from outside of the Milky Way\, also known as the extragalactic background light (EBL)\, traces star formation back to the Epoch of Reionization (EOR) and provides important constraints to cosmological models. Near-infrared data from Spitzer and the sounding rocket experiment CIBER-1 suggest that the observed EBL fluctuates more than predicted by galaxy models. Multiple sources have been proposed to reconcile the differences between observations and theories. In particular\, CIBER-1 data can be explained by considering contribution from faint stars known as the intra-halo light (IHL). To study the IHL and distinguish it from EOR signals\, the next generation CIBER-2 is designed with significant improvements in wavelength coverage and sensitivities. CIBER-2 was first launched onboard the Black Brant IX vehicle in June 2021 to collect data between 0.5 – 2.0 microns. The experiment is currently being refurbished for the next launch. In this talk\, I will discuss CIBER-2 design\, characterization\, integration\, and progress after the first flight. \nZoom Link: \nhttps://zoom.us/j/3199318714?pwd=ZlV3VCsraHpYeGpIRlYwY2hEaU5Gdz09 \n\nMeeting ID: 319 931 8714\nPasscode: sagi2022

SUMMARY:Simon Coudé (Harvard)
DESCRIPTION:Dr. Simon Coudé (Harvard) \nTitle: \nRevealing the dynamics of star-forming regions with far-infrared polarization \nAbstract: \nThe polarization signature from dust thermal emission in the far-infrared is a powerful tool to study the physical properties of star-forming environments\, and specifically to reveal the role of magnetic fields in slowing the gravitational collapse of interstellar filaments. With its multi-wavelength polarimetric capabilities\, the High-resolution Airborne Wideband Camera Plus (HAWC+) aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) therefore opened a unique window into the dynamics of stellar nurseries during its lifetime. In particular\, the Filaments Extremely Long and Dark: A Magnetic Polarization Survey (FIELDMAPS) with HAWC+ provided detailed maps of dust polarization at 214 µm in ten of the largest known filaments in the Milky Way galaxy. These observations provide the highest resolution measurements to date of the magnetic field in these dense filamentary structures\, also described as the “bones” of our Galaxy. Using the Davis-Chandrasekhar-Fermi (DCF) technique and the Angular Dispersion Function (ADF)\, combined with ancillary spectroscopic data of dense gas tracers in each bone\, to quantify the magnetic field amplitude across these filaments. Furthermore\, polarization measurements at multiple wavelengths can also improve our understanding of dust physics by probing their alignment efficiency to interstellar magnetic fields\, which emphasizes the importance of the synergy of HAWC+ observations with longer-wavelength data from other observatories.

SUMMARY:Yue Hu (UW-Madison)
DESCRIPTION:Speaker: Yue Hu (UW-Madison) \nTitle: Characterizing 3D Magnetic Fields in Star-Forming Regions \nMagnetic field\, turbulence\, and self-gravity are important in understanding star formation. However\, 3D magnetic field orientation and strength were barely accessed. Based on our recent understanding of dust polarization and anisotropic MHD turbulence\, I will present two novel methods\, i.e.\, polarization fraction analysis and velocity gradient technique (VGT)\, in tracing the 3D magnetic field orientation. By combing with the Davis–Chandrasekhar-Fermi method\, I will show that the 3D magnetic field distribution\, including both orientation and strength\, is successfully recovered in the low-mass star-forming region L1688. The second method\, VGT employs spectroscopic emission lines to derive the magnetic field. I will show that VGT-measurement advantageously gets rid of the contribution from the cloud’s foreground/background. By using multiple molecular tracers\, VGT reveals the magnetic field’s variation in different volume density regimes. I will also discuss magnetic fields’ role in fueling galactic nuclei.

SUMMARY:Brandon Hensley (Princeton)
DESCRIPTION:Title: The Nature of Interstellar Dust: Insights from Polarimetry \nAbstract: \nWhat is interstellar dust made of? In this talk\, I will argue against conventional models that posit dust grains come in separate silicate and carbonaceous varieties. Rather\, I will use observations of polarized dust emission to argue that grains are a mix of both silicate and carbonaceous materials\, as well as other materials like metallic iron and iron oxides. Tests of this hypothesis and implications for the lifecycle of dust in the interstellar medium will be highlighted.

DESCRIPTION:Speaker: Dr. Pham Tuan Anh (Viet Nam National Space Center)\n\nVenue: Online via Zoom\nTime: 2:00 pm – 3:00 pm\, Oct 20th\, 2022\n\n\n\nTitle: Study of high-redshift galaxies at Department of Astrophysics (DAP/VNSC)\n\nAbstract:The presentation covers research work done in the Department of Astrophysics of the Vietnam National Space Centre (DAP/VNSC) on high redshift galaxies in the early Universe. After a brief general introduction\, including research interests and methods\, in particular gravitational lensing\, I will present radio interferometer studies using open-access ALMA observations of two quasar hosts\, RX J0911.4+0551 and RX J1131\, which illustrate well how the morpho-kinematics of their gas and dust components can be explored using millimetre continuum and line emissions. I will then turn to our present work\, in collaboration with the Laboratoire d’Astrophysique de Marseille\, in the frame of the MUSE Collaboration. MUSE stands for Multi Unit Spectroscopic Explorer and uses observations made by the Very Large Telescope (VLT) in the visible. It identifies and studies the first galaxies in the early Universe and their contribution to cosmic re-ionization. Finally\, I will present results covering measurements of the Luminosity Function of ~600 Lyman-alpha Emitters probing down to 10^40 erg/s based on deep observations of 17 lensing clusters. This unique dataset will allow for placing strong constraints on the contribution of the LAE population to cosmic reionization.

SUMMARY:Archana Soam (India Institute of Astrophysics)
DESCRIPTION:Speaker: Prof. Archana Soam (India Institute of Astrophysics)\n\n\nTitle: Threads & flows in the dusty universe: Importance of astronomical polarimetry and spectroscopy in probing star-forming regions\n \nAbstract:\n\nThe role of magnetic fields (B-fields) and turbulence in star formation is still under debate\, but considering the magnetized nature of molecular clouds\, we expect B-fields to have a significant impact on this process. Observations of molecular clouds in different environments using different astronomical techniques helps in understanding the various important aspects of star formation. I mostly worked towards mapping B-fields in nearby low-mass star-forming regions in different environments viz. molecular clouds in isolation and HII regions at their different evolutionary stages using multi-band polarization observations. This was done using optical\, near-IR\, and sub-mm polarization observations to map B-fields from pc to sub-pc scales. In this talk\, I will briefly present my work on B-fields in various Galactic regions i.e. cores\, filaments\, and HII regions.  We know that grain alignment is the key to understand interstellar dust polarization. Therefore\, I will mostly emphasize on my recently accomplished work on the investigation of grain alignment efficiency in PDRs using dust polarization measurements.\n\n\nZoom link:\n\n\nICISE SAGI is inviting you to a scheduled Zoom meeting.\n\nTopic: SAGI SeminarTime: Sep 26\, 2022 11:00 AM VietnamJoin Zoom Meetinghttps://zoom.us/j/3199318714?pwd=ZlV3VCsraHpYeGpIRlYwY2hEaU5Gdz09Meeting ID: 319 931 8714Passcode: sagi2022

ALMA observations reveal the diverse properties of dust polarization with wavelengths and location\, which suggests the presence of different polarization mechanisms in protostellar environments. In this talk\, I will briefly review the current status of ALMA dust polarization observations and discuss perspectives on this research topic.\n

SUMMARY:Webinar: A Search for Neutron-Antineutron Oscillation in the NOvA experiment
DESCRIPTION:Title: A Search for Neutron-Antineutron Oscillation in the NOvA experiment\nSpeaker: Dr. Dung Phan\, Uni.v of Texas at Austin\, US\n \nAbstract: Searching for neutron-antineutron oscillation is an active research direction that promises immense values for field of particle physics and cosmology. An experimental observation of the phenomenon offers the possibility of new physics associated with anomalous B and/or B − L violating processes. A data-driven trigger that allows NOvA – a long baseline neutrino oscillation experiment – to collect the neutron-antineutron oscillation candidates will be described in detail. An analysis approach in which the real data is partially unblinded to assist the development and evaluation of the event selection and background normalization is chosen for this search. Due to the fact that this is an ongoing work and important aspects of the analysis has not been all finalized\, we conclude with a sensitivity study. By analyzing the data from 4 months of the NOvA’s Far Detector exposure\, a 90% C.L. sensitivity limit of 4 × 1030 years was placed on the oscillation life-time of bound neutrons from the 12C targets. This is equivalent to a sensitivity of 0.57 × 108 s placed on the oscillation life-time of free neutrons. \n \nWebinar page: https://ifirse.icise.vn/nugroup/event/20200903_nova_neutronosc.html\nZoom connection: \nhttps://us02web.zoom.us/j/86228803171?pwd=ZWltUXZDajVZNUlMWnExNzJRVVZKdz09Meeting ID: 862 2880 3171/Passcode: 17082020

SUMMARY:Webinar: CP violation in neutrino oscillations and Leptogenesis
DESCRIPTION:A joint theoretical & experimental webinar:\nCP violation in neutrino oscillations and leptogenesis\nDate/time: Aug. 20th\, 2020\, 9:00-11:00 GMT+7 (VN timezone)\nConnection: https://us02web.zoom.us/j/84449657519?pwd=cFVKOWZ2N04vVFhYUElkTStBWUE5QT09\nMeeting ID: 844 4965 7519\nPasscode: 19871998 \n  \nTalk#1: Leptogenesis and Low Energy CP Violation\, Jessica Turner\, Fermilab\, US\nI will provide a general overview of the matter anti-matter asymmetry and how this can be linked to the generation of light neutrino masses. I will discuss the possibility of producing the observed baryon asymmetry of the Universe via thermal leptogenesis\, where CP violation comes exclusively from the low-energy phases of the neutrino mixing matrix. We demonstrate the viability of thermal leptogenesis across seven orders of magnitude 106 < T (GeV)< 1013. We clarify that at very high scales T > 1012 GeV is sensitive to the low-energy phases\, in contradiction with what is usually claimed in the literature. \n  \nTalk#2: Neutrino Physics in Japan with a gigantic detector\, Super-Kamiokande\, Tsuyoshi Nakaya\, Kyoto Univ.\, JP\nNeutrinos are mysterious particles in our universe. We observe neutrinos from the Sun\, Atmosphere\, Supernova\, Reactors\, and Accelerators. In the study of neutrinos\, we explore particle physics\, astrophysics\, and cosmology. In Japan\, neutrino physics is very popular with two Nobel prizes: One is to Prof. Masatoshi Koshiba with the observation of supernova neutrinos and the second is to Prof. Takaaki Kajita with the discovery of neutrino oscillations. In this webinar\, we introduce Neutrino Physics in Japan conducted with a gigantic neutrino detector\, Super-Kamiokande. Super-Kamiokande is the detector by which we discover neutrino oscillations from atmospheric neutrinos. Besides\, Super-Kamiokande observes neutrinos from Sun and accelerators. In Japan\, we have a powerful accelerator (called J-PARC) that provides the most intense neutrino beam in the world. By using the accelerator neutrino beam\, we conduct the neutrino experiment T2K to study neutrino oscillations in detail. We report the Super-K and T2K experiments in the webinar. In 2020\, a new and larger detector than Super-Kamiokande\, “Hyper-Kamiokande”\, is approved in Japan for further studies of neutrinos. We also introduce the Hyper-Kamiokande project briefly. \n  \n

SUMMARY:Webinar: Probing few-body nuclear dynamics vis 3H and 3He (e\,e’p)pn cross-section
DESCRIPTION:We will have a webinar from Dr. Dien Nguyen\, MIT & J-Lab regarding to their recent publication\nhttps://journals.aps.org/prl/abstract/10.1103/PhysRevLett.124.212501\n\nThe title and abstract are included in the following. We are interested in this work because there is a strong connection between the neutrino vs. electron interaction model in which the current & future neutrino program depends on it to explore the physics such as CP violation\, mass hierarchy…Some connections can be found at Neutrino 2020 talk last week.\nhttps://indico.fnal.gov/event/43209/contributions/187820/attachments/130254/158595/200623_e4nu_neutrino2020.pdf\n\n\n\n———————\n\nTitle: Probing few-body nuclear dynamics vis 3H and 3He (e\,e’p)pn cross-section\n\nAbstract:\n\n“In this presentation we will report the first measurement of the (e\,e’p) three-body breakup reaction cross sections in helium-3 (3He) and tritium (3H) at large momentum transfer (Q 2  ~ 1.9 (GeV/c)2) and (xB > 1) kinematics\, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40 < pmiss < 500 MeV/c that\, in the QE limit with no rescattering\, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab-initio calculations. Overall good agreement\, within _20%\, is observed between data and calculations for the full pmiss range for 3H and for 100 < pmiss < 350 MeV/c for 3He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at pmiss > 250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of 3He plus 3H\, which is largely insensitive to SCX\, is described by calculations to within the accuracy of the data over the entire pmiss range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.”\n\n — \n \n\nFeel free to forward the webinar info. to your colleagues who may be interested in.\n\n\n—————— \n\n\nTime: Jul 3\, 2020 10:00 AM Vietnam\n\nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/81872540539?pwd=dGZQdFJtdHJvQXZHVlE4WlhpVGUwQT09\n\nMeeting ID: 818 7254 0539\nPassword: 17072017\n\nSlides can be found at 20200703_dien_escattering.pdf

SUMMARY:IFIRSE colloquium
DESCRIPTION:Connection: https://zoom.us/j/506363139\nSeminar#1 (9:00-9:45):  Einstein-Podolsky-Rosen paradox\, Bell inequalities\, entanglement and quantum steering \nSpeaker: Dr. Chau Nguyen\, University of Siegen (Siegen\, Germany) / [slides] (file is protected by a password )\nIn 1935\, Einstein\, Podolsky and Rosen described a thought experiment illustrating that quantum mechanics can deeply disturb our very intuition of locality\, eventually leading them to regard quantum mechanics as being incomplete. We give a simple introduction to the Einstein-Podolsky-Rosen thought experiment\, followed by insights given by Schrödinger and a short (and necessarily incomplete) introduction to their further implications. We then discuss the modern approaches: Bell inequalities\, separability\, quantum steering\, and their imprints in the theory of quantum information processing and the foundation of quantum mechanics. In the latter part of the the talk\, we emphasise on quantum steering\, the most recent and most closely related approach to the Einstein-Podolsky-Rosen original intuition. Technical characterisation of quantum steering\, the role of measurements and generalised measurements\, and the effects of dimensionality will be discussed. \n  \nSeminar#2 (10:00-10:45): (d\,p) reactions based on Faddeev-Alt-Grassberger-Sandhas formalism\nSpeaker: Dr. Tran Viet Nhan Hao\, Hue University\, Hue\, Viet Nam / [slides]\nIn nuclear reactions\, Faddeev-Alt-Grassberger-Sandhas (FAGS) equations are well known the only existing formalism which can describe simultaneously and exactly the elastic\, inelastic\, and rearrangement process.  However\, the most performance FAGS code is still limited at the medium targets due to the long-range character of Coulomb interaction. In this talk\, we discuss our efforts to overcome this barrier. Also\, we make a review of recent progress in developing the microscopic optical potential which is a crucial ingredient for the (d\,p) codes. \n
