Abstract

Abstract: We report the results of a detailed analysis of a deep simultaneous $130\, \rm ks$ XMM–Newton and NuSTAR observation of the nearby ($z$ = 0.0315) and bright ($L_{\rm bol}\sim 3\times 10^{45}\, \rm erg\, s^{-1}$ ) starburst–active galactic nucleus (AGN) Seyfert 2 system: MCG–03–58–007. From the broad-band fitting we show that most of the obscuration needs to be modelled with a toroidal type reprocessor such as MYTorus . None the less the signature of a powerful disc-wind is still apparent at higher energies and the observed rapid short-term X-ray spectral variability is more likely caused by a variable zone of highly ionized fast wind rather than by a neutral clumpy medium. We also detect X-ray emission from larger scale gas as seen from the presence of several soft narrow emission lines in the RGS, originating from a contribution of a weak star-forming activity together with a dominant photoionized component from the AGNs.
