Mapping SMBH Winds, from the Event Horizon up to Galaxy Scales
Abstract
Powerful winds driven by active galactic nuclei (AGN) are often invoked to play a fundamental role in the evolution of both supermassive black holes (SMBHs) and their host galaxies, possibly quenching star formation and explaining the tight SMBH-galaxy relations. Additional support for this "quasar-mode" feedback came from new X-ray observations of mildly relativistic disk winds, a.k.a. ultrafast outflows, in some ultra-luminous infrared galaxies and their connection with galactic molecular outflows observed in mm and IR wavebands. In particular, the combination of X-ray (Suzaku, NuSTAR), IR (Herschel), and mm (ALMA) observations of IRAS F11119+3257 allowed us to link the SMBH activity to molecular outflows that may quench star formation. Therefore, synergistic observations in X-ray and other wavebands have the power to map AGN winds from the event horizon up to galaxy scales, providing a promising avenue to study the multiphase SMBH feeding and feedback. Revolutionary improvements are expected from upcoming X-ray space observatories, such as Athena and XARM, in synergy with other major space- and ground-based facilities.
