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: The first indications of a class of long GRBs are presented, which form a bridge between the typical high-luminosity, high-redshift events and nearby low- luminosity events (which are also associated with spectroscopic supernovae) in terms of energetics and observed redshift distribution, indicating a continuous distribution overall.

TL;DR: Ultraviolet and x-ray observations of a binary neutron star merger show a hot kilonova but no jet along the line of sight, which avoids both obscuration from the heaviest elements in the orbital plane and a direct view of any ultrarelativistic, highly collimated ejecta.

TL;DR: In this article, a large sample of GRB afterglow and prompt-emission data was used to compare the optical afterglows (or lack thereof) of Type I GRBs with those of Type II GRBs.

TL;DR: Spectral analysis of the Swift observations of GRB 060614 shows that the burst presents standard optical, ultraviolet and X-ray afterglows, detected beginning 4 ks after the trigger, and that the peak energy of the burst has decreased to as low as 8 keV at the beginning of the XRT observation.
