Supercomputers Help Uncover 'Noisy' Neutron Star Collisions


Aug 14, 2020

David Radice, a Pennsylvania State University astrophysics assistant professor working as member of the Computational Relativity International Collaboration or CoRe, which includes scientists in the U.S., Germany, Italy, and Brazil, wanted to better understand the phenomenon of unequal neutron stars colliding, and to predict signatures of such collisions that astronomers could look for.
