Constraints on the absorption-dominated model for the X-ray spectrum of MCG-6-30-15 (2009)
Reynolds, Christopher S., Fabian, Andrew C., Brenneman, Laura W., Miniutti, Giovanni, Uttley, Phil, Gallo, Luigi C.
Complexities in the X-ray spectrum of the nearby Seyfert 1.2 galaxy MCG-6-30-15 are commonly interpreted in terms of a broad iron line and the associated Compton reflection hump from the innermost...
Porquet, Delphine, Uttley, Phil, Reeves, James N., Markowitz, Alex, Bianchi, Stefano, Grosso, Nicolas, ...
(Abridged) We present here a long (100ks) XMM-Newton follow-up of the Seyfert 1.8 galaxy ESO113-G010 performed in November 2005, in order to study over a longer time-scale its main X-ray properties....
Eight powers of ten: similarities in black hole accretion on all mass scales (2007)
Fender, Rob, Koerding, Elmar, Belloni, Tomaso, Uttley, Phil, McHardy, Ian, Tzioumis, Tasso
In this paper we discuss the recent advances in the quantitative comparison of accretion, and the accretion:jet coupling, in accreting black holes in both X-ray binaries (where M ~ 10Msun) and Active...
Quasi-Periodic Variability in NGC 5408 X-1 (2007)
Strohmayer, Tod E., Mushotzky, Richard F., Winter, Lisa, Soria, Roberto, Uttley, Phil, Cropper, Mark
We report the discovery with XMM-Newton of quasiperiodic variability in the 0.2 - 10 keV X-ray flux from the ultraluminous X-ray source NGC 5408 X-1. The average power spectrum of all EPIC-pn data...

Constraints on AGN accretion disc viscosity derived from continuum variability (2003)
Starling, Rhaana L. C., Siemiginowska, Aneta, Uttley, Phil, Soria, Roberto
We estimate a value of the viscosity parameter in AGN accretion discs for the PG quasar sample. We assume that optical variability on time-scales of months to years is caused by local instabilities...
Correlated long-term optical and X-ray variations in NGC 5548 (2003)
Uttley, Phil, Edelson, Rick, McHardy, Ian, Peterson, Bradley M., Markowitz, Alex
We combine the long-term optical light curve of the Seyfert 1 galaxy NGC5548 with the X-ray light curve measured by the Rossi X-ray Timing Explorer over 6 years, to determine the relationship between...
