Title: | A new candidate for a powerful wind detected in a bright IR-galaxy | Authors: | BRAITO, Valentina Reeves, J. SEVERGNINI, Paola DELLA CECA, Roberto Matzeu, G. Ballo, L. NARDINI, EMANUELE |
Issue Date: | 2017 | Volume: | The X-ray Universe 2017 | First Page: | 45 | Abstract: | We report the discovery of a new candidate for a powerful disk wind, in a nearby and bright starburst-AGN system: MCG-03-58-007. The winds strongly resembles the case of PDS456. MCG-03-58-007 is a relatively X-ray bright Seyfert 2 galaxy for which a deep Suzaku observation unveiled a highly curved spectrum due to a high column density absorber and an extremely steep intrinsic photon index (Gamma = 3). A detailed analysis showed that the steep spectrum is mainly driven by the presence of a deep absorption trough at 7.5-9 keV. This could be accounted for by the presence of a high ionisation, fast (v up to 0.2c) outflowing wind launched from within a few 100Rg from the black hole, whose kinetic output matches the prescription for significant feedback. New deep simultaneous XMM-Newton and NuSTAR observations provided the first direct measurement of the AGN luminosity and more importantly confirms the presence of a powerful X-ray wind. The new observations show rapid spectral variability, whose main driver appears to be the wind itself. | Conference Name: | The X-ray Universe 2017 | Conference Place: | Rome, Italy | Conference Date: | 6-9 June, 2017 | URI: | http://hdl.handle.net/20.500.12386/26647 | URL: | https://www.cosmos.esa.int/documents/332006/1402684/VBraito_t.pdf https://www.cosmos.esa.int/web/xmm-newton/2017-symposium |
