Galactic Centre at 20-40 keV

January 7, 2013
ISGRI images of the Galactic Centre in the 20-40 keV band. The analysis of ISGRI data is based on GCDE and GPS data from revolution 30 to 64 (11 January to 22 April 2003) for a total of one thousand pointings (about 2 Msec exposure). Not all the sources are labeled for clarity. The sources labeled in white belong to the monitoring program of the Bright LMXRB group. (Courtesy A. Paizia et al) Date: 16 Oct 2003 Copyright: ESA
