Abstract

Owing to its wide sky coverage and broad energy range, the FermiGamma-ray Burst Monitor (GBM) is an excellent observer of the transient hardX-ray sky. GBM detects about 240 triggered Gamma-Ray Bursts (GRBs) per year, includingover 30 which also trigger the Swift Burst Alert Telescope (BAT). Thenumber of GRBs seen in common with Swift is smaller than expected fromthe overlap in sky coverage because GBM is not as sensitive as the BAT and the GBM GRBpopulation is thus skewed to the brighter, closer bursts. This population includes about45 short GRBs per year, giving GBM an excellent opportunity to observe the electromagneticcounterpart to any gravitational wave candidate resulting from the merger of compactbinary members. The same characteristics make GBM an ideal partner for neutrino searchesfrom nearby GRBs, and for the elusive Very-High Energy (VHE) counterparts to GRBs. Withthe deployment of the next-generation gravitational-wave detectors (Advanced LIGO/VIRGO)and VHE experiments (CTA and HAWC) potentially within the lifetime of the FermiGamma-ray Space Telescope, the prospects for breakthrough observations aregood.
