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 …

The cosmic origin of elements heavier than iron has long been uncertain. Theoretical
modelling,,,,,, shows that the matter that is expelled in the violent merger of two neutron stars …

We present optical and ultraviolet spectra of the first electromagnetic counterpart to a
gravitational-wave (GW) source, the binary neutron star merger GW170817. Spectra were …

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 …

On 17 August 2017, Swope Supernova Survey 2017a (SSS17a) was discovered as the
optical counterpart of the binary neutron star gravitational wave event GW170817. We report …

The rapid neutron capture process (r process) is believed to be responsible for about half of
the production of the elements heavier than iron and contributes to abundances of some …

The detection of the binary neutron star merger GW170817 together with the observation of
electromagnetic counterparts across the entire spectrum inaugurated a new era of …

Seconds-long numerical-relativity simulations for black hole–neutron star mergers are
performed for the first time to obtain a self-consistent picture of the merger and post-merger …

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 …
