The highly variable X-ray spectrum of the luminous Seyfert 1 galaxy 1H 0419-577
K. L. Page, K. A. Pounds, J. N. Reeves +1
An XMM-Newton observation of the luminous Seyfert 1 galaxy 1H 0419-577 is presented. We find that the spectrum is well fitted by a power law of canonical slope (gamma ~ 1.9) and 3…
An XMM-Newton observation of the extreme Narrow Line Seyfert 1 Galaxy, Mrk 359
P. T. O'Brien, K. Page, J. N. Reeves +3
We present XMM-Newton observations of Mrk 359, the first Narrow Line Seyfert 1 galaxy discovered. Even among NLS1s, Mrk 359 is an extreme case with extraordinarily narrow optical e…
An XMM-Newton observation of the luminous Seyfert 1 galaxy Markarian 509
Ken Pounds, James Reeves, Paul O'Brien +3
We present the spectral analysis of an early XMM-Newton observation of the luminous Seyfert 1 galaxy Markarian 509. We find the hard (2-10 keV) continuum slope, including reflectio…
The identification of an optical counterpart to the super-Eddington X-ray source, NGC 5204 X-1
T. P. Roberts, M. R. Goad, M. J. Ward +4
We report the identification of a possible optical counterpart to the super-Eddington X-ray source NGC 5204 X-1. New Chandra data shows that the X-ray source is point-like, with a…
Monitoring of the optical and 2.5-11.7 micron spectrum and mid-IR imaging of the Seyfert 1 galaxy Mrk279 with ISO
The AGN Watch collaboration, M. Santos-Lleo, J. Clavel +19
Mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the 2.5-11.7 micron…
