The lively accretion disc in NGC 2992. III. Tentative evidence of rapid Ultra Fast Outflow variability
Alfredo Luminari, Andrea Marinucci, Stefano Bianchi +8
We report on the 2019 XMM-Newton+NuSTAR monitoring campaign of the Seyfert galaxy NGC 2992, observed at one of its highest flux levels in the X-rays. The time-averaged spectra of t…
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…
Poynting-Robertson effect on black-hole-driven winds
M. Marzi, F. Tombesi, A. Luminari +2
Layers of ionized plasma, in the form of winds ejected from the accretion disk of Supermassive Black Holes (SMBHs) are frequently observed in Active Galactic Nuclei (AGNs). Winds w…
