چکیده
We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806-20 and 190 lesser events from SGR 1806-20 and SGR 1900+14. The unprecedented sensitivity of the detectors allows us to set the most stringent limits on transient GW amplitudes published to date. We find upper limit estimates on the model-dependent isotropic GW emission energies (at a nominal distance of 10 kpc) between 3x10;{45} and 9x10;{52} erg depending on waveform type, detector antenna factors and noise characteristics at the time of the burst. These upper limits are within the theoretically predicted range of some SGR models.

Searching for Gravitational-Wave Bursts with LIGO
We present recent results from searches by the LIGO Science Collaboration for bursts of gravitational-wave radiation, as well as the status of other ongoing searches. These include directed searches for bursts associated with observed sources (gamma-ray bursts, soft gamma repeaters) and untriggered searches for bursts from unknown sources. We also present the status of some newer investigations...
متن کاملDo soft gamma repeaters emit gravitational waves ?
Soft gamma repeaters are identified as highly magnetized (B≈ 10 14 Gauss) neutron stars. Magnetic stresses induce tectonic activity, and field annihilation in faults is the ultimate energy source for the observed γ-ray emission. As a consequence of the crustal cracking, the stored elastic energy is converted into high frequency (kHz) shear waves, that excite nonradial oscillation modes damped b...

متن کاملSearch for time correlation between gamma-ray bursts and data from the gravitational wave antenna EXPLORER
An analysis of the time correlation between Gamma-Ray Bursts from BATSE detector and EXPLORER Gravitational Wave Antenna data was performed from april 1991 to december 1996. A time interval of ±5 minutes around the trigger time of Gamma-Ray Bursts (GRBs) was explored. No significant excess of coincidences between GRBs and EXPLORER events with an energy of about 100 mK was found. This result all...
متن کاملTesting the Fireball/blastwave Model by Monitoring Afterglows from Soft Gamma Repeaters
The popular fireball/blastwave model of classical γ-ray bursts is applied to soft γ-ray bursts. It is found that X-ray afterglows from strong events may be above their quiescent levels for 40 − 400 seconds. Optical afterglows may also be detectable. By monitoring the three repeaters, we will have an ideal way to check the fireball/blastwave model.
متن کاملA BATSE-based search for repeaters in the sample of gamma-ray bursts detected by the WATCH experiment
This study is the first known attempt to search for gamma-ray burst repeaters combining data from gamma-ray experiments flying on board different satellites and making use of information derived from the bursts detected simultaneously by all the experiments. The proposed method is suitable to correlate GRB data provided by experiments that overlap partially or totally in time. As an application...
