Energetics of the superflare from SGR1806-20 an a possible associated gravitational wave burst

Abstract
We discuss in this Letter the energetics of large gamma-ray superflares observed from Soft-Gamma Repeater sources. The last recorded event has in fact ruled out some models for the energy release. For the first time actual information about a possible associated gravitational wave emission may be gathered from the LIGO data, even in the case that most of the energy was emitted in gamma-rays. Even upper limits on the amplitude of the latter at the expected frequency may be useful to further constrain the remaining mechanisms
To appear in Mod. Phys. Lett. A - Two broadband detectors apparently online at the time of the event. Due to more restrictive criteria and slightly different assumptions the figures reported here may differ from actual ones by a small numerical factor.
