Supermassive Black Hole Winds in X-rays: SUBWAYS. II. HST UV spectroscopy of winds at intermediate redshifts
M. Mehdipour, G. A. Kriss, M. Brusa +35
We present a UV spectroscopic study of ionized outflows in 21 active galactic nuclei (AGN), observed with the HST. The targets of the SUBWAYS sample were selected with the aim to p…
Supermassive Black Hole Winds in X-rays -- SUBWAYS. I. Ultra-fast outflows in QSOs beyond the local Universe
G. A. Matzeu, M. Brusa, G. Lanzuisi +48
We present a new X-ray spectroscopic study of luminous () active galactic nuclei (AGNs) at intermed…
A New Emulated Monte Carlo Radiative Transfer Disk-Wind Model: X-Ray Accretion Disk-wind Emulator -- XRADE
G. A. Matzeu, M. Lieu, M. T. Costa +14
We present a new X-Ray Accretion Disk-wind Emulator (\textsc{xrade}) based on the 2.5D Monte Carlo radiative transfer code which provides a physically-motivated, self-consistent tr…
Repeating tidal disruptions in GSN 069: Long-term evolution and constraints on quasi-periodic eruptions' models
G. Miniutti, M. Giustini, R. Arcodia +4
GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) have been identified. These are high-amplitude, soft X-ray bursts recurring every ~9 hr, lasting ~1 hr,…
The Super-Massive Black Hole close environment in Active Galactic Nuclei
W. Alston, M. Giustini, P. O. Petrucci
Active Galactic Nuclei are powered by accretion of matter onto a supermassive black hole (SMBH) of mass Mbh ~ 10^{5}-10^{9} Msun. The accretion process is indeed the most efficient…
The complex time and energy evolution of quasi-periodic eruptions in eRO-QPE1
R. Arcodia, G. Miniutti, G. Ponti +8
Quasi-periodic eruptions (QPEs) are recurrent X-ray bursts found so far in the nuclei of low-mass galaxies. Their trigger mechanism is still unknown, but recent models involving on…
