TL;DR: A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.

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: Tanvir et al. as mentioned in this paper used the United Kingdom Infrared Telescope, Hawaii, from about 20 minutes after the burst and arrive at z ≈ 8.2, implying that massive stars were being produced and dying as GRBs approximately 620 million years after the Big Bang.

TL;DR: Zhang et al. as discussed by the authors reported that GRB 060614 was not accompanied by supernova emission down to limits hundreds of times fainter than the archetypal supernova SN 1998bw that accompanied GRB 980425, and faintter than any type Ic supernova ever observed.

TL;DR: GROND as discussed by the authors is a 7-channel imager designed for rapid observations of gamma-ray burst afterglows at the MPI/ESO 2.2m telescope at La Silla (Chile).
