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…
Probing black-hole accretion through time variability
Barbara De Marco, Sara E. Motta, Tomaso M. Belloni
Flux variability is a remarkable property of black hole (BH) accreting systems, and a powerful tool to investigate the multi-scale structure of the accretion flow. The X-ray band i…
The lively accretion disk in NGC 2992. II. The 2019/2021 X-ray monitoring campaigns
R. Middei, A. Marinucci, V. Braito +8
We report on the short and long term X-ray properties of the bright nearby Seyfert 2 galaxy NGC 2992, which was extensively observed with Swift, XMM-Newton and NuSTAR. Swift target…
Transient obscuration event captured in NGC 3227 III. Photoionization modeling of the X-ray obscuration event in 2019
Junjie Mao, J. S. Kaastra, M. Mehdipour +16
A growing number of transient X-ray obscuration events in type I AGN suggest that our line-of-sight to the central engine is not always free. Multiple X-ray obscuration events have…
X-ray variability of transitional millisecond pulsars: a faint, stable and fluctuating disk
Manuel Linares, Barbara De Marco, Rudy Wijnands +1
Transitional millisecond pulsars (tMSPs) have emerged in the last decade as a unique class of neutron stars at the crossroads between accretion- and rotation-powered phenomena. In…
The X-ray spectral-timing contribution of the stellar wind in the hard state of Cyg X-1
E. V. Lai, B. De Marco, A. A. Zdziarski +6
The clumpy stellar wind from the companion star in high mass X-ray binaries causes variable, partial absorption of the emission from the X-ray source. We studied XMM-Newton observa…
