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) …

What is the origin of the oxygen we breathe, the hydrogen and oxygen (in form of water
H2O) in rivers and oceans, the carbon in all organic compounds, the silicon in electronic …

The production of elements by rapid neutron capture (r-process) in neutron-star mergers is
expected theoretically and is supported by multimessenger observations,–of gravitational …

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 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.▪ …

The observations of GW170817/AT2017gfo have provided us with evidence that binary
neutron star mergers are sites of r-process nucleosynthesis. However, the observed …

Abstract We present Chandra and Very Large Array observations of GW170817 at∼ 521–
743 days post-merger, and a homogeneous analysis of the entire Chandra data set. We find …

For the first∼ 3 yrs after the binary neutron star merger event GW 170817, the radio and X-
ray radiation has been dominated by emission from a structured relativistic off-axis jet …

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 …

The late-time spectra of the kilonova AT 2017gfo associated with GW170817 exhibit a strong
emission line feature at. The line structure develops with time and there is no blueshifted …
