Elucidating the global distribution of reprocessing gas in NGC 1194

T. J. Turner, J. N. Reeves, V. Braito +3

A joint XMM-Newton and NuSTAR observation was conducted for the bright, local Seyfert 1.9 galaxy, NGC 1194. The hard spectral form of this AGN was modeled using the toroidal reproc…

X-ray variability analysis of a large series of XMM-Newton + NuSTAR observations of NGC 3227

A. P. Lobban, T. J. Turner, J. N. Reeves +2

We present a series of X-ray variability results from a long XMM-Newton + NuSTAR campaign on the bright, variable AGN NGC 3227. We present an analysis of the lightcurves, showing t…

Astro2020 Science White Paper: Do Supermassive Black Hole Winds Impact Galaxy Evolution?

F. Tombesi, M. Cappi, F. Carrera +11

Powerful winds driven by supermassive black holes (SMBHs) are likely the main mechanism through which SMBHs regulate their own growth and influence the host galaxy evolution. Howev…

A rapid occultation event in NGC 3227

T. J. Turner, J. N. Reeves, V. Braito +3

NGC 3227 exhibits rapid flux and spectral variability in the X-ray band. To understand this behaviour we conducted a co-ordinated observing campaign using 320 ks of XMM-Newton expo…

A new powerful and highly variable disk wind in an AGN-star forming galaxy, the case of MCG-03-58-007

V. Braito, J. N. Reeves, G. A. Matzeu +7

We present the discovery of a new candidate for a fast disk wind, in the nearby Seyfert 2 galaxy MCG-03-58-007. This wind is discovered in a deep Suzaku observation that was perfor…

On the Nature of the High-Energy Rollover in 1H 0419-577

T. J. Turner, J. N. Reeves, V. Braito +1

A NuSTAR/Swift observation of the luminous Seyfert 1 galaxy 1H 0419-577 taken during 2015 reveals one of the most extreme high energy cut-offs observed to date from an AGN - an ori…
