Binary Neutron Star Mergers - IPAM at UCLA

Explore the fascinating world of binary neutron star mergers in this 48-minute lecture by David Radice from Pennsylvania State University. Delve into the current theoretical understanding of neutron star merger dynamics and their multimessenger emissions. Examine recent simulation results and their implications for answering fundamental questions in theoretical astrophysics, such as the nature of neutron stars and the formation of r-process elements in the Universe. Learn about the merger process, including dynamical mass ejection, disk formation, and postmerger evolution. Discover how multimessenger observations can provide constraints on the equation of state and other key parameters. Investigate challenges in the field and future prospects, including computational advancements like GRAthena++. Gain insights into this cutting-edge research presented at IPAM's Workshop I: Computational Challenges in Multi-Messenger Astrophysics at UCLA.
