Dynamical complexity in micro-scale disk-wind systems
Fabrizio Fiore, Massimo Gaspari, Alfredo Luminari +2
Powerful winds at accretion-disk scales have been observed in the past 20 years in many AGN. These are the so-called ultrafast outflows (UFOs). Outflows are intimately related to m…
Unraveling Baroclinicity in Black Hole Weather Storms
