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…
Breaking the rules at 0.45: the rebel case of RBS 1055
A. Marinucci, G. Vietri, E. Piconcelli +5
We report on a long (250 ks) NuSTAR observation of the bright quasar RBS 1055 performed in March 2021, and archival XMM-Newton pointings (185 ks) taken in July 2014. An optical spe…
Supermassive Black Holes at High Redshift are Expected to be Obscured by their Massive Host Galaxies' Inter Stellar Medium
R. Gilli, C. Norman, F. Calura +12
We combine results from deep ALMA observations of massive () galaxies at different redshifts to show that the column density of their inter stellar medium (…
Compton-Thick AGN in the NuSTAR era VIII: A joint NuSTAR-XMM-Newton monitoring of the changing-look Compton-thick AGN NGC 1358
Stefano Marchesi, Xiurui Zhao, Núria Torres-Albà +18
We present the multi-epoch monitoring with NuSTAR and XMM-Newton of NGC 1358, a nearby Seyfert 2 galaxy whose properties made it a promising candidate X-ray changing look AGN, i.e.…
An X-ray fading, UV brightening QSO at
Fabio Vito, Marco Mignoli, Roberto Gilli +13
Explaining the existence of SMBHs at is a persistent challenge to modern astrophysics. Multi-wavelength observations of QSOs revea…
The properties of the X-ray corona in the distant () quasar APM 08279+5255
E. Bertola, C. Vignali, G. Lanzuisi +7
We present new joint XMM-Newton and NuSTAR observations of APM 08279+5255, a gravitationally-lensed, broad-absorption line quasar (). After showing a fairly stable flux ($f…
