Collective neutrino flavor oscillations in supernovae from a many body perspective (E. Rrapaj) (Opens in a new window)

IReNA online seminar

Seminars

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.

CANCELLED: MSU Science Festival Expo (Opens in a new window)

Biomedical and Physical Sciences Building, Michigan State University

Outreach

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!

New Results on Stellar Neutrinos (F. Timmes) (Opens in a new window)

IReNA online Seminar

Seminars

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.

CANCELLED: The building blocks of matter: atoms or LEGOs? (Opens in a new window)

Michigan History Center, 702 W Kalamazoo St, Lansing, MI 48915

Outreach

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 The pattern of stable and radioactive nuclei will help explain the how the matter in your body was originally made in stars!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)

Santa Fe, NM

Workshops & Conferences

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.

POSTPONED - Frontiers in Nuclear Astrophysics 2020 (Opens in a new window)

Embassy Suites, South Bend, IN

Workshops & Conferences

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.

Stellar Modelling for Nuclear Astrophysics (Opens in a new window)

Louisiana State University

Workshops & Conferences

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.

Astrophysics with Radioactive Isotopes (AwRI2020) (Opens in a new window)

Budapest, Hungary

Workshops & Conferences

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).

Taking the Temperature: Statistical Nuclear Physics for Astrophysics and Applications (T3) (Opens in a new window)

Ohio University, Athens, Ohio

Workshops & Conferences

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.

16th International Symposium on Nuclei in the Cosmos (Opens in a new window)

Chengdu, China

School
Workshops & Conferences

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.
