Events at Physics
In this period of time, GBM has triggered and located on average approximately two GRBs every three days. The most recent results are summarized in the latest two catalogs provided by the Fermi GBM science team, namely the third GBM GRB catalog and the first GBM time-resolved spectral catalog.<br><br>
Moreover, the Fermi LAT science team has been recently performing an extensive search for GRBs at high energies (>100 MeV) featuring a detection efficiency more than 50% better than previous works, and returning more than 130 detections.<br><br>
Finally, I'll present the GBM and LAT follow-up of the LIGO Gravitational Wave event GW 150914, focusing on the GBM detection of a weak transient event, close in time to the LIGO one. Future joint observations of GW events by LIGO/Virgo and Fermi could reveal whether the weak transient reported by GBM is a plausible counterpart to GW150914 or a chance coincidence, and will further probe the connection between compact binary mergers and short GRBs.
