Latest News From The Integral Galactic Bulge Monitoring Program
Abstract
The central region of our Galaxy, the Galactic bulge, is a rich host of variable high-energy X-ray and gamma-ray point sources. These sources include bright and relatively faint X-ray transients, X-ray bursters, persistent neutron star and black-hole candidate binaries, high-mass X-ray binaries, etc.. We have a program to monitor the Galactic bulge region regularly and frequently with the gamma-ray observatory INTEGRAL, whenever it is observable. As a service to the scientific community the high-energy light curves of sources present, as well as the images of the region, are made available through the WWW (http://integral.esac.esa.int/BULGE/) as soon as possible after the
observations have been performed; all the data are public immediately. We show the ongoing results of this exciting program, including observations of the shortest orbital period black-hole X-ray binary transient MAXI J1659-152 and the evolution of the spin period over 3 decades of high-energy astrophysics of the symbiotic X-ray binary pulsar GX 1+4.- Publication:
