Abstract

We present results from Swift, XMM-Newton, and deep INTEGRAL monitoring (AO-5 key program data) in the region of GRB 050925. This short Swift burst is a candidate for a newly discovered soft gamma-ray repeater (SGR) with the following observational burst properties: 1) galactic plane (b=-0.07°) localization, 2) 150 msec duration, and 3) a blackbody rather than a simple power-law spectral shape. We will show a possible X-ray counterpart of GRB 050925, and also the results of searching ∼ 1 Msec INTEGRAL data for persistent hard X-ray emission from this SGR candidate source.
