SUMMARY:The Fermi view of Gamma-Ray Bursts & the curious case of GW 15
 0914\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Elisabetta Bissaldi
  \, Politecnico & INFN Bari
DESCRIPTION:I'll give a brief overview of Gamma-Ray Bursts (GRBs) obse
 rvations performed over the past 8 years by the two instruments on-boa
 rd the Fermi satellite\, namely the Gamma-Ray Burst Monitor (GBM) and 
 the Large Area Telescope (LAT).<br><br><br>
\nIn 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>
 <br>
\nMoreover\, the Fermi LAT science team has been recently perform
 ing 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><br>
\nFinally\, I'll pres
 ent the GBM and LAT follow-up of the LIGO Gravitational Wave event GW 
 150914\, focusing on the GBM detection of a weak transient event\, clo
 se 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.
