Description

During Galactic Center survey program by IBIS telescope on-board INTEGRAL the supernova remnant RX J1713.7-3046 was observed in hard X-ray band (17-60 keV) for the first time. The surface brightness maps of the supernova remnant in 17-27-36-50-120 and 17-60 keV energy bands will presented in this talk. The spectra of two brightest clumps of RX J1713.7-3946 are characterized by a power law spectrum with photon index ~3. The surface brightness map of RX J1713.7-3946 in soft X-ray band (1-10 keV), based on the XMM-Newton observations (2001–2017), demonstrates good agreement with that obtained by IBIS telescope, which points out to a single mechanism working in soft and hard X-rays. The XMM-Newton spectrum of RX J1713.7-3046 in the 0.8-10 keV band is well described by the power-law model with photon index ~2, which indicates a change of the spectral slope somewhere between 10 and 17 keV. The value of the slope change (or high-energy cutoff) contains important information about the acceleration efficiency of cosmic ray particles in the supernova remnant.
