Description
Supermassive black hole (SMBH) winds are believed to be a key player in the evolution of galaxies. In fact, outflows from active galactic nuclei (AGN) may be one of the fundamental mechanisms by which a SMBH transfers a significant fraction of its accretion energy to the surrounding environment. Disk-scale ionized ultra-fast outflows (UFOs) and large-scale warm absorbers (WAs) are commonly found in the X-ray spectra of many Seyfert galaxies and quasars. Even though a correlation between these two absorbers has been suggested in the past, a direct link is still missing. Here we present the analysis of 12 XMM-Newton EPIC spectra in which, together with WA and UFO, we found a 'low-ionization UFO'. This absorber has the same velocity as the UFO (
