Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

Two types of gamma-ray bursts (GRBs) are observed: short-duration hard spectrum GRBs
and long-duration soft spectrum GRBs. For many years long GRBs were the focus of intense …

We present a new moment-based energy-integrated neutrino transport code for neutron star
merger simulations in general relativity. In the merger context, ours is the first code to include …

Mergers of neutron stars (NS+ NS) or neutron stars and stellar-mass black holes (NS+ BH)
eject a small fraction of matter with a subrelativistic velocity. Upon rapid decompression …

Two neutron stars merge somewhere in the Universe approximately every 10 to 100 s,
creating violent explosions potentially observable in gravitational waves and across the …

Black hole (BH) accretion discs formed in compact-object mergers or collapsars may be
major sites of the rapid-neutron-capture (r-) process, but the conditions determining the …

GW170817 and GRB 170817A provided direct evidence that binary neutron star (NSNS)
mergers can produce short gamma-ray bursts (sGRBs). However, questions remain about …

This article presents a comprehensive overview of numerical hydrodynamics and magneto-
hydrodynamics (MHD) in general relativity. Some significant additions have been …

Recent equations of state for dense nuclear matter are discussed with possible phase
transitions arising in neutron stars such as pion, kaon and hyperon condensation …

▪ Abstract High-energy (> 100 MeV) neutrino astrophysics enters an era of opportunity and
discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We …
