Nature's Ultimate Hadron Collider: Neutron Star Mergers

David Radice, Dept. Astrophysical Sciences, Princeton University, NJ
Bldg. 6008 Large Conference Room

Neutron star mergers are among the most violent events in the Universe. Gravitational wave, electromagnetic, and neutrino signals from these mergers encode important aspects of the physics of neutron stars, which cannot be inferred from terrestrial laboratory experiments. For example, on the nature of the short-range interaction between nucleons, which is imprinted in the neutron star equation of state, or on the origin of the heavy elements. However, harnessing these imminent detections will only be possible by combining the observational data with reliable theoretical predictions, which, in turn, rely on the availability of high-precision simulations. In this talk, I will present new results on the modeling of neutron star mergers as gravitational-wave sources and as short gamma-ray burst progenitors and I will discuss current challenges and future perspectives in this field.
