Gravitational Wave Burst Search in LIGO: Methods and Results
Laura Cadonati, Massachusetts Institute of Technology

The Laser Interferometer Gravitational-wave Observatory (LIGO) Burst Analysis
group is pursuing searches for un-modeled gravitational-wave transients of short
duration (< 1 sec) in the 100-2000 Hz frequency band. Plausible sources of this
type of signal are core-collapse supernovae and the merger and ring-down
phases of coalescing binary systems. In this talk I will describe the methods
used in this search to optimize the detection efficiency and to suppress the false
alarm rate with minimal assumptions on the signal's morphology. I will present
the most recent upper limit results and discuss possible future directions for the
LIGO burst analysis.
