High energy sources monitored with OMC

Abstract

During the last five years, the Optical Monitoring Camera (OMC) on-board INTEGRAL has been observing the optical counterparts of high energy sources. In this contribution we present the results for some of the most interesting sources analyzed up to now, mostly X-ray binary systems, discussing the correlation between the optical and the high energy (X and gamma-rays) emission. We also describe the capabilities of the OMC Data Center at http://sdc.laeff.inta.es/omc, from which all optical light curves obtained by OMC can be previewed and easily downloaded. In this paper we present the light curves of the X-ray binaries:
