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.

Polarization of Gravitational Waves in General Teleparallel Theories of Gravity

TL;DR: In this article, the possible gravitational wave polarizations in two general classes of teleparallel gravity theories were determined using the Newman-Penrose formalism, and it was shown that depending on the choice of parameters, the E(2) class of theories is one of N2,N3, III5, II6, corresponding to two to six polarizations, where all of them include the two tensor polarizations known from general relativity.

Using negative-latency gravitational wave alerts to detect prompt radio bursts from binary neutron star mergers with the Murchison Widefield Array

TL;DR: In this paper, the authors examined how fast radio burst (FRB)-like signals predicted to be generated during the merger of a binary neutron star (BNS) may be detected in low-frequency radio observations triggered by the aLIGO/Virgo gravitational wave detectors.

Effects of the merger history on the merger rate density of primordial black hole binaries

TL;DR: In this article, the authors developed a formalism to calculate the merger rate density of primordial black hole binaries with a general mass function, by taking into account the merger history of prim-ordial black holes.

Spin-induced deformations and tests of binary black hole nature using third-generation detectors

TL;DR: Krishnendu et al. as discussed by the authors employed a non-precessing post-Newtonian (PN) waveform model to assess the capabilities of the third-generation gravitational wave interferometers such as Cosmic Explorer and Einstein Telescope, and used them to test the binary black hole nature of observed binaries.
