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…
TPHO: a time-dependent photoionisation model for AGN outflows
Daniele Rogantini, Missagh Mehdipour, Jelle Kaastra +3
Outflows in active galactic nuclei (AGN) are considered a promising candidate for driving AGN feedback at large scales. However, without information on the density of these outflow…
Multi-wavelength observations of the obscuring wind in the radio-quiet quasar MR 2251-178
Junjie Mao, G. A. Kriss, H. Landt +11
Obscuring winds driven away from active supermassive black holes are rarely seen due to their transient nature. They have been observed with multi-wavelength observations in a few…
Oxygen and iron in interstellar dust: an X-ray investigation
I. Psaradaki, E. Costantini, D. Rogantini +9
Understanding the chemistry of the interstellar medium (ISM) is fundamental for the comprehension of the Galactic and stellar evolution. X-rays provide an excellent way to study th…
The multi-epoch X-ray tale of I Zwicky 1 outflows
Daniele Rogantini, Elisa Costantini, Luigi Gallo +3
The narrow-line Seyfert 1 galaxy I Zwicky 1 shows a unique and complex system of ionised gas in outflow, which consists of an ultra-fast wind and a two-component warm absorber. In…
