TL;DR: In this article, the effects of possible systematic errors in the waveform models on estimates of its source parameters were investigated and no evidence for a systematic bias relative to the statistical error of the original parameter recovery of GW150914 due to modeling approximations or modeling inaccuracies was found.

TL;DR: In this article, the authors describe directed searches for continuous gravitational waves in data from the sixth LIGO science data run, where the targets were nine young supernova remnants not associated with pulsars; eight of the remnants are associated with non-pulsing suspected neutron stars.

TL;DR: In this article, features of the signal visible in the data are analyzed using concepts from Newtonian physics and general relativity, accessible to anyone with a general physics background, consistent with the fully general-relativistic analyses published elsewhere, showing that the signal was produced by the inspiral and subsequent merger of two black holes.

TL;DR: In this article, the authors derived the first constraints on the progenitor of GW170817 at the time of the second supernova (SN) and found these constraints to be comparable to those for Galactic BNS progenitors.

TL;DR: In this paper, the first and second observing runs of the Advanced LIGO and Virgo detector network were used to obtain the first standard-siren measurement of the Hubble constant.
