SUBWAYS
Supermassive Black Hole Winds
in X-rays
Artistic view of multiphase AGN-driven winds highlighting the different phases and scales that are involved in the outflow. The wind propagates from the central engine (< 1 pc; a), through the surrounding ISM (1 pc–1 kpc; b), out to the boundaries of the host galaxy (> 10 kpc; c). SUBWAYS investigates the outflow in its launching phase, when the gas is highly ionized, and the presence of fast-moving material can be revealed in X-rays.

SUBWAYS
The SUBWAYS project (an acronym for “Supermassive Black Holes Winds in the X-rays”) collected XMM-Newton observations during AO18 for more than 400 hours (1.46 Ms) to observe a sample of 17 quasars at redshift z~0.1-0.4, i.e. in a cosmic epoch (the past 1-4 Gyr) where the presence and properties of AGN-driven winds has not yet been explored in the X-rays with the needed accuracy. Archival XMM-Newton observations of another five QSOs were used to expand the sample to 22 targets in total.
