Detection of Soft Gamma-ray Emission from XTE J1752-223 and Other Hard Sources with GBM
Abstract
The Gamma-Ray Burst Monitor (GBM) onboard Fermi is being used to monitor hard x-ray/soft gamma-ray sources using the Earth occultation technique. Through the first 15 months of this monitoring program, seven sources have been detected at energies above 100 keV. In particular, the transient source XTE J1752-223, which was discovered by RXTE on October 23, 2009, was detected above 100 keV during its outburst. Light curves of all seven sources are presented using the 8-channel CTIME data with particular discussion of XTE J1752-223.
