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…
A Systematic View of Ten New Black Hole Spins
Paul A. Draghis, Jon M. Miller, Abderahmen Zoghbi +4
The launch of NuSTAR and the increasing number of binary black hole (BBH) mergers detected through gravitational wave (GW) observations have exponentially advanced our understandin…
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…
Comparing Reflection and Absorption Models for the Soft X-ray Variability in the NLS1 AGN UGC 11763
Jiachen Jiang, Luigi C. Gallo, Dirk Grupe +1
We present a spectral analysis of two XMM-Newton observations of the narrow-line Seyfert 1 galaxy UGC 11763. UGC 11763 shows very different soft X-ray spectral shapes in the two ob…
The Low Temperature Corona in ESO 511G030 Revealed by NuSTAR and XMM-Newton
Zuobin Zhang, Jiachen Jiang, Honghui Liu +9
We present the results from a coordinated XMM-Newton NuSTAR observation of the Seyfert 1 Galaxy ESO 511G030. With this joint monitoring programme, we conduct a detailed vari…
A truncated inner disc in the Seyfert 1 galaxy WKK 4438
L. C. Gallo, M. Z. Buhariwalla, J. Jiang +2
Understanding if and when the accretion disc extends down to the innermost stable circular orbit (ISCO) is important since it is the fundamental assumption behind measuring black h…
