LIGO-Virgo events localization as a test of gravitational wave polarization state

Abstract

Detection of the first gravitational wave events GW150914, GW151226 and LVT151012 by Advanced LIGO antennas has opened new possibility for study the fundamental physics of the gravitational interaction. Actual localization on the sky a source of gravitational wave by means of measurements of the arrival time delays between antennas together with relative amplitudes of the detected signals at each antenna can be used for determination the polarization state of the gravitational wave. The sky-circles of allowed positions of the GW sources for detected three LIGO events are parallel to the supergalactic plane of the disc-like large scale structure known as Local Super-Cluster of galaxies having radius \(\sim 80\) Mpc and thickness \(\sim 30\) Mpc. This points to a possibility for reconsideration of distances to these GW sources.
