TLDR
For the first time, the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network is tested, thus enabling a new class of phenomenological tests of gravity.
Abstract
On August 14, 2017 at 10∶30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of ≲1 in 27 000 years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio of 18. The inferred masses of the initial black holes are 30.5-3.0+5.7M⊙ and 25.3-4.2+2.8M⊙ (at the 90% credible level). The luminosity distance of the source is 540-210+130  Mpc, corresponding to a redshift of z=0.11-0.04+0.03. A network of three detectors improves the sky localization of the source, reducing the area of the 90% credible region from 1160   deg2 using only the two LIGO detectors to 60  deg2 using all three detectors. For the first time, we can test the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network, thus enabling a new class of phenomenological tests of gravity.

How post-Newtonian dynamics shape the distribution of stationary binary black hole LISA sources in nearby globular clusters

TL;DR: In this paper, the authors derived the observable GW peak frequency distribution of binary black holes (BBHs) that currently reside inside their globular clusters (GCs), with and without 2.5 post-Newtonian (2.5 PN) effects included in the dynamical evolution of the BBHs.

Towards a framework for testing general relativity with extreme-mass-ratio-inspiral observations

TL;DR: This work adapts and applies a generalised model for extreme-mass-ratio inspirals constructed on deformed black-hole spacetimes to find order-of-magnitude computational gains over regular nested sampling in the case of synthetic data generated from the null model.
