TL;DR: The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.

TL;DR: In this article, the authors reported 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 Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) and as a short gamma-ray burst by Fermi Gamma-ray Burst Monitor (GBM) and Integral SPI-ACS (GRB 170817A).

TL;DR: In this paper, ultraviolet and x-ray observations from the Nuclear Spectroscopic Telescope Array (NSTA) of the binary neutron star merger GW170817 were used to detect a high mass (≈0.03 solar masses) wind-driven outflow with moderate electron fraction.

TL;DR: Measurements of wavelength-resolved iron opacity at electron temperatures and electron densities at the solar radiation/convection zone boundary show that wavelength-dependent opacity is 30–400 per cent higher than predicted, which represents roughly half the change in the mean opacity needed to resolve the solar discrepancy.
