Abstract

Short Gamma-Ray Bursts (sGRB) are thought to originate from accreting stellar-mass black holes resulting from compact mergers. The gravitational waves emitted during such close-by merger events will be observable after 2015 by the next generation detectors (Advanced LIGO/Virgo). The Gamma-Ray Burst Monitor (GBM) on-board the Fermi space telescope will complement these detectors, providing the gamma-ray counterparts to graviational waves detections.

GBM currently observes 45 sGRB per year, many of them likely close-by, and some of these are therefore likely to be within the Advanced LIGO/Virgo horizon for detecting compact mergers. In addition to on-board triggers, a ground search for short transients can soon be performed, since the data for individual GBM photon collected over the full orbit will be available. We provide predictions for the rate of joint detections by GBM and the Advanced LIGO/Virgo detectors, and present consequences for the study of the sources of these multi-messenger emissions.
