Picture of the Month 

September 2003

Since the galactic center is currently visible for INTEGRAL most of the observations taking place this month are of the Galactic Center. The image is an IBIS/ISGRI image of the Galactic Centre in the 20-40 keV band. The analysis of IBIS/ISGRI data is based on GCDE (Galactic Center Deep Exposure) and GPS (Galactic Plane Scan) data from revolution 30 to 64 i.e. January 11th to April 22nd, 2003 for a total of one thousand pointings (about 2 Msec exposure). Not all the sources are labeled for clarity.

This figure is taken from a paper by Paizis et al. (http://arXiv.org/abs/astro-ph/0308038), describing the first INTEGRAL results on persistent neutron star binaries. This paper will appear in a special Astronomy & Astrophysics issue devoted to INTEGRAL.
