Gamma Ray Burst Observations with LIGO Laura Cadonati, University of Massachusetts, Amherst Frontiers of Space Astrophysics: Neutron Stars & Gamma Ray Bursts Cairo and Alexandria, Egypt, March 30 - April 4 2009 The LIGO and Virgo laser interferometers are preparing for the operation of enhanced detectors at unprecedented sensitivity. At the beginning of the observational era, the most interesting science will come from multi-messenger observations, where the gravitational wave signal has an electromagnetic counterpart. In particular, Gamma Ray Bursts have been the focus of LIGO searches since the early days of its data acquisition, with templated searches for compact binary coalescences for short GRBs and unmodeled burst searches, to cover other possible models for both short and long GRBs. Information on the time and location of the progenitor is used to increase the sensitivity of the search and, in the event of a detection, confidence in the result. In this talk, I will review LIGO's effort for the observation of Gamma Ray Bursts, with methods, interpretations and prospects, in the upcoming era of Enhanced and Advanced LIGO.
