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 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 …

Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the
Universe. The duration and hardness distribution of GRBs has two clusters, now understood …

We describe the first observations of the same celestial object with gravitational waves and
light.▪ GW170817 was the first detection of a neutron star merger with gravitational waves.▪ …

Probing the origin of r-process elements in the universe represents a multidisciplinary
challenge. We review the observational evidence that probes the properties of r-process …

Abstract We present James Webb Space Telescope (JWST) and Hubble Space Telescope
(HST) observations of the afterglow of GRB 221009A, the brightest gamma-ray burst (GRB) …

We perform radiative transfer simulations for kilonova in various situations, including the
cases of prompt collapse to a black hole from neutron star mergers, high-velocity ejecta …

Mergers of binaries consisting of two neutron stars, or a black hole and a neutron star, offer a
unique opportunity to study a range of physical and astrophysical processes using two …

We report our identification of the optical afterglow and host galaxy of the short-duration
gamma-ray burst sGRB 160821B. The spectroscopic redshift of the host is z= 0.162, making …

Gamma-ray bursts (GRBs) are classified into long and short events. Long GRBs (LGRBs)
are associated with the end states of very massive stars, while short GRBs (SGRBs) are …
