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.▪ …

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 …

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 …

Neutron star mergers are unique laboratories of accretion, ejection, and r-process
nucleosynthesis. We used 3D general relativistic magnetohydrodynamic simulations to …

After being launched, gamma-ray burst (GRB) jets propagate through dense media prior to
their breakout. The jet-medium interaction results in the formation of a complex structured …

We present a revised and complete optical afterglow light curve of the binary neutron star
merger GW170817, enabled by deep Hubble Space Telescope (HST) F606W observations …

Due to relativistic bulk motion, the structure and orientation of gamma-ray burst (GRB) jets
have a fundamental role in determining how they appear. The recent discovery of the …

In the new era of gravitational wave (GW) and multi-messenger astrophysics, the detection
of a GW signal from the coalescence of a black hole–neutron star (BHNS) binary remains a …
