The production of about half of the heavy elements found in nature is assigned to a specific
astrophysical nucleosynthesis process: the rapid neutron-capture process (r process) …

The mergers of double neutron star (NS–NS) and black hole (BH)–NS binaries are
promising gravitational wave (GW) sources for Advanced LIGO and future GW detectors. The …

A long-standing paradigm in astrophysics is that collisions—or mergers—of two neutron
stars form highly relativistic and collimated outflows (jets) that power γ-ray bursts of short …

With the first direct detection of merging black holes in 2015, the era of gravitational wave
(GW) astrophysics began. A complete picture of compact object mergers, however, requires …

We report the discovery and monitoring of the near-infrared counterpart (AT2017gfo) of a
binary neutron-star merger event detected as a gravitational wave source by Advanced …

The coalescence of double neutron star (NS–NS) and black hole (BH)–NS binaries are
prime sources of gravitational waves (GW) for Advanced LIGO/Virgo and future ground …

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 …

We examine the effect of neutrino flavor transformation by the fast flavor instability (FFI) on
long-term mass ejection from accretion disks formed after neutron star mergers. Neutrino …

The mergers of binary neutron stars, as well as black hole–neutron star systems, are
expected to produce an electromagnetic counterpart that can be analyzed to infer the …

The kilonova (KN) associated with the binary neutron star (BNS) merger GW170817 is the
only known electromagnetic counterpart to a gravitational wave source. Here we produce a …
