New Transients as Detected by the Fermi Gamma-Ray Burst Monitor, January-June 2011
Abstract
After analyzing data collected by the Fermi Gamma Ray Space Telescope Gamma-Ray Burst Monitor (GBM), operated by NASA in cooperation with the US Department of Energy, we focus on transient gamma ray events from January of 2011. A number of these events were detected in concordance with events that have already been reported, and the others are analyzed in this report. For each event detected with a trigger-search computer algorithm, an energy spectrum was generated and these spectra were divided into several categories for further analysis. In some cases, intriguing spectral lines, including a 511 keV line, were detected, implications and analysis of these known and previously unknown events are discussed
