Data pubblicazione: | 2019 | Rivista: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Numero: | 483 | Fascicolo: | 2 | Da pagina:: | 2836 | Abstract: | We report the results of a detailed analysis of a deep simultaneous 130 ksXMM-Newton and NuSTAR observation of the nearby (z = 0.0315) and bright (L_bol∼ 3× 10^{45} 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. | URI: | http://hdl.handle.net/20.500.12386/29309 | URL: | https://academic.oup.com/mnras/article/483/2/2836/5234249 | ISSN: | 0035-8711 | DOI: | 10.1093/mnras/sty3327 | Bibcode ADS: | 2019MNRAS.483.2836M | Fulltext: | open |
