Well, gravitational waves were detected by the advanced Laser Interferometer Gravitational-Wave Observtory, or LIGO for short. The study was based on the observation of difference in time taken by light to travel in the event of a space time distortion. ...
Were the redshift distribution for GRBs the same as that for quasars, one would expect several of these to have been gravitationally lensed. The search techniques and potential discoveries are presented in Sect. 4.5.2. 3.3.4 Gravitational Waves Since the first detection of gravitational waves (...
Notably, the announcement of gravitational waves [3,4], the first black hole shadow image of M87∗ and Sag A* by the EHT collaboration [5–7], and the motion of S-stars around the galactic center [8–10] have sparked much interest in the scientific community to study further the ...
