Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously
with core-collapse supernovae (SNe), thus linking by a common thread nature's two …

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 …

Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and
mechanism are the focus of intense research and debate. More than three decades after …

We present the first comprehensive study of r-process element nucleosynthesis in the ejecta
of compact binary mergers (CBMs) and their relic black hole (BH)–torus systems. The …

We investigate the long-term evolution of black hole accretion discs formed in neutron star
mergers. These discs expel matter that contributes to an r-process kilonova, and can …

Mergers of binary neutron stars and black hole–neutron star binaries are among the most
promising sources for ground-based gravitational-wave (GW) detectors and are also high …

With its rapid-response capability and multiwavelength complement of instruments, the Swift
satellite has transformed our physical understanding of γ-ray bursts (GRBs). Providing high …

Expulsion of neutron-rich matter following the merger of neutron star binaries is crucial to the
radioactively powered electromagnetic counterparts of these events and to their relevance …

Binary neutron star mergers observations are a unique way to constrain fundamental
physics and astrophysics at the extreme. The interpretation of gravitational-wave events and …

We review the formation and evolution of compact binary stars consisting of white dwarfs
(WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are …
