Abstract

Gravitational Waves from SGR Bursts

Soft gamma repeaters (SGRs) have unique properties that make them intriguing GW targets.  They are nearby, their burst emission mechanism may involve neutron star crust fractures and excitation of non-radial modes, and they burst repeatedly and sometimes spectacularly.  Recent LIGO searches for transient GW from these sources have placed upper limits on a set of more than 200 individual SGR bursts from SGR 1900+14 and SGR 1806-20 including the 2004 giant flare; have stacked potential signals from the 2006 SGR 1900+14 storm to place improved upper limits on that event; and have examined recent activity from SGR 0501+4516 which may be only 1.5 kpc from Earth. We present the results from these searches, and discuss the astrophysics that is beginning to emerge from SGR GW searches.
