TL;DR: The spectral identification and physical properties of a bright kilonova associated with the gravitational-wave source GW170817 and γ-ray burst GRB 170817A associated with a galaxy at a distance of 40 megaparsecs from Earth are described.

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: It is reported that a supernova was associated with the ultra-long-duration γ-ray burst GRB 111209A, at a redshift z of 0.677, and this supernova is more than three times more luminous than type Ic supernovae associated with long-duration μ-ray bursts, and its spectrum is distinctly different.

TL;DR: In this article, the sky localization of the first observed compact binary merger is presented, where the authors describe the low-latency analysis of the LIGO data and present a sky localization map.

TL;DR: In this paper, the authors used the afterglow detection statistics of the systematic follow-up observations performed with GROND since mid-2007 in order to derive the fraction of dark gamma-ray bursts according to different methods, and distinguish between various scenarios for “dark bursts”.
