A ~1-hour X-ray periodicity in an active galaxy RE J1034+396
Marek Gierlinski, Matthew Middleton, Martin Ward +1
Active galactic nuclei and quasars are thought to be scaled up versions of Galactic black hole binaries, powered by accretion onto supermassive black holes with masses of 10^6-10^9…
An absorption origin for the soft excess in Seyfert 1 AGN
M. J. Middleton, C. Done, M. Gierlinski
(abridged) The soft excess seen in the X-ray spectra of many high mass accretion rate AGN can be well modelled by reflection from a partially ionised accretion disc. However, the d…
Black hole spin in GRS 1915+105
Matthew Middleton, Chris Done, Marek Gierlinski +1
Microquasars are galactic black hole binary systems with radio jets which can sometimes be spatially resolved to show superluminal motion. The first and best known of this class of…
