Abstract:

Continuous Time-Tagged Events (CTTE) Data have been collected since November 2012. Those data are ideal to search shorter intervals and use more sophisticated algorithms to find weaker events. Here I present our preliminary results on searching un-triggered short GRB events from the two-year CTTE data. A preliminary un-triggered sGRB catalog is presented. Their durations, locations, populations, and implications for the overlap between SGRBs observed by Fermi and gravitational wave candidates detected in the aLIGO/VIRGO era will be discussed.
