Prospects about X- and gamma-ray counterparts of gravitational wave signals with INTEGRAL

Philippe Bacon, Volodymyr Savchenko, Eric Chassande-Mottin

By extrapolating the number of detections made during the first LIGO science run, tenths of gravitational wave signals from binary black hole mergers are anticipated in upcoming LIGO Virgo science runs. Finding an electromagnetic counterpart to compact binary merger events would be a landmark discovery. The search for such counterpart is challenging for a number of reasons, such as the poor resolution of source position reconstruction from the gravitational wave observations alone, and the weakness of the expected electromagnetic signal. In this poster, we evaluate the ability of current wide-field X- and gamma-ray telescopes aboard INTEGRAL to find such counterparts. We present the result of an end-to-end simulation for estimating the fraction of the sources that can be followed up, and the fraction of counterparts that can be detected based on different models.
