Abstract

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 from compact binary merger events would be a capital achievement. We evaluate the ability of current wide-field X- and gamma-ray telescopes aboard INTEGRAL to find such counterparts thanks to an end-to-end simulation for estimating the fraction of the sources that can be followed up and/or detected.
