Collective neutrino flavor oscillations in supernovae from a many body perspective (E. Rrapaj) (Opens in a new window)
Presented by Ermal Rrapaj from the University of Minnesota
Abstract: I study the flavor evolution of a dense neutrino gas by considering vacuum contributions, mat-ter effects and neutrino self-interactions. Assuming a system of two flavors in a uniform matter background, the time evolution of the many-body system in discretized momentum space is com-puted. The multi-angle neutrino-neutrino interactions are treated exactly and compared to both the single-angle approximation and mean field calculations. I study various configurations of up to twenty neutrinos.
The 8th annual MSU Science Festival will take place April 1-30, 2020. Presenters are getting ready to dazzle, delight, educate, and inform, reaching beyond science to include technology, engineering, arts, and mathematics (STEAM) and the important role they play shaping our future and everyday lives. The April 4 expo will feature dozens of booths, and JINA will be on hand to demonstrate nuclear astrophysics with hands-on activities!
Abstract: Over the next decade, neutrino astronomy will probe the rich astrophysics of neutrino production in the sky, including neutrinos from the Sun, core-collapse supernova (e.g., SN 1987A), and relativistic jets (e.g., blazar TXS 0506+056). On the observational side of this new era, the Super-Kamiokande with Gadolinium, Jiangmen Underground Neutrino Observatory, XENON, and future liquid scintillator neutrino experiments usher in a new generation of multi-purpose neutrino detectors designed to open new avenues for potentially observing currently undetected neutrinos.
Each year units, departments and colleges across MSU’s campus participate in the Take Your Child to Work Day event. JINA will offer a short lesson about rare isotopes!
The periodic table organizes atoms into different elements, but the chart of nuclides is a better way to classify them. Discover the secrets of the nucleus by building a chart from towers of LEGO bricks, one for each of 130 isotopes in the first ten elements. The pattern of stable and radioactive nuclei will help explain the how the matter in your body was originally made in stars! Hosted by the Michigan History Museum and sponsored by the MSU Science Festival.
POSTPONED - International Workshop on Nuclear Statistical Physics in Astrophysics and Nuclear Applications (NuSPANA) (Opens in a new window)
We are organizing an international workshop on Nuclear Statistical Physics in Astrophysics and Nuclear Applications (NuSPANA). Nuclear reaction data is one of the key elements in nuclear applications ranging from simulating nucleosynthesis in stellar modeling to performance validation in nuclear energy and nuclear security. Experimental effort in the Los Alamos Neutron Science Center (LANSCE) is focused on neutron-induced reactions, in close collaboration with reaction theory development and continuous progress on cross-section evaluations at LANL.
The Seminar will begin at 2pm EST
Online Seminar featuring Rana Ezzeddine (MIT)
This will be the tenth in a series of former JINA and now JINA-CEE meetings that brings together JINA-CEE participants, collaborators, and other interested researchers in nuclear physics, astronomy, and astrophysics to discuss progress and future directions related to the understanding of the origin of the elements and neutron stars.

This workshop intends to teach the application of stellar modelling using Modules for Experiments in Stellar Astrophysics (MESA) to those in the nuclear-astrophysics community. This is especially geared toward those in the nuclear community who measure, calculate, and theorize reaction rates, in order to apply them to existing stellar models and measure the effects on various features, such as abundances and other astronomical observables.
Radioactive nuclei play a significant role in many current astrophysical quests. From the origin of the elements through the driving of the emissions from supernovae (56Ni) and kilonovae (r-process radioactivity), they are crucial for direct studies of galactic enrichment (7Be, 26Al, 44Ti, 60Fe, 99Tc, 244Pu, ...) and for new insights on stellar explosions (56/57Ni, 44Ti).
We would like to invite you to participate in a JINA-CEE sponsored workshop on all things R-matrix that will be held from June 22 - 26, 2020 at Ohio University in Athens, OH, USA.
Taking the Temperature: Statistical Nuclear Physics for Astrophysics and Applications (T3) (Opens in a new window)
Statistical estimates of nuclear reaction rates are essential ingredients for astrophysical model calculations, e.g. r-process nucleosynthesis in neutron star mergers, and nuclear applications, e.g. next generation nuclear reactor performance. Rate calculations require experimental or theoretical constraints for nuclear properties such as level densities (temperature), gamma-strength functions, particle optical potentials, and level spin distributions.
Nuclei in the Cosmos is the most important international meeting in the field of nuclear astrophysics. It brings together nuclear experimentalists, nuclear theorists, astronomers, theoretical astrophysicists, cosmo-chemists, and others interested in the scientific questions at the interface of nuclear physics and astrophysics. These questions concern, for example, the origin of the elements in the cosmos and the nuclear reactions that occur in the big bang, in stars, and in stellar explosions.
