The outflowing ionised gas of I Zw 1 observed by HST COS
A. Juráňová, E. Costantini, G. A. Kriss +8
We present an analysis of the HST COS spectrum of IZw1 aiming to probe the absorbing medium associated with the active galactic nucleus (AGN). We fitted the emission spectrum and p…
Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows
V. E. Gianolli, S. Bianchi, P-O Petrucci +44
The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…
Study of the optical to X-ray broad emission lines of Mrk 110
A. Juráňová, E. Costantini, L. Di Gesu +7
In order to shed light on the characteristics of the broad line region (BLR) in a narrow-line Seyfert 1 galaxy, we present an analysis of X-ray, UV, and optical spectroscopic obser…
Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability
S. Grafton-Waters, J. Mao, M. Mehdipour +13
Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…
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…
