High energy emission from IGR J16320-4751
Abstract
IGR J16320-4751 was re-discovered by IBIS/ISGRI on board INTEGRAL in early February 2003 during the observation of the black hole candidate 4U 1630-47 (PI Tomsick). This source, already observed by ASCA and BeppoSAX, belongs to the class of heavily absorbed objects (N_H > 10^23 cm^-2) that populate some arms of the Galaxy. Soon after the rediscovery by IBIS/ISGRI, the source was observed by XMM-Newton: the arcsec position found with XMM allowed ones to find the most likely infrared counterpart. We present here the reanalysis of the high energy emission from IGR J16320-4751 detected by IBIS/ISGRI, including the spectral and temporal characteristics. We also present a reanalysis of the XMM-Newton and optical/IR data.
