Characterizing the UV and X-ray Outflow in Mrk 509
G. A. Kriss, N. Arav, J. S. Kaastra +15
We observed Mrk 509 during the fall of 2009 during a multiwavelength campaign using XMM-Newton, Chandra, HST/COS, SWIFT, and Integral. The 600-ks XMM/RGS spectrum finds two kinemat…
Multiwavelength campaign on Mrk 509. VI. HST/COS observations of the far-ultraviolet spectrum
G. A. Kriss, N. Arav, J. S. Kaastra +15
We present medium resolution (R~20,000) HST/COS ultraviolet spectra covering 1155-1760 A of the Seyfert 1 Mrk 509 obtained simultaneously with a Chandra/LETGS spectrum as part of a…
Multiwavelength campaign on Mrk 509. IV. Optical-UV-X-ray variability and the nature of the soft X-ray excess
Missagh Mehdipour, Graziella Branduardi-Raymont, Jelle S. Kaastra +8
We present the analysis of XMM-Newton and Swift optical-UV and X-ray observations of the Seyfert-1/QSO Mrk 509, part of an unprecedented multi-wavelength campaign, investigating th…
Multiwavelength campaign on Mrk 509. I. Variability and spectral energy distribution
J. S. Kaastra, P. -O. Petrucci, M. Cappi +23
(Abridged) Active galactic nuclei show a wealth of interesting physical processes, some of which are poorly understood. We want to address a number of open questions, including the…
The nature of X-ray absorbed QSOs
M. J. Page, F. J. Carrera, J. A. Stevens +2
There exists a significant population of broad line, z~2 QSOs which have heavily absorbed X-ray spectra. Follow up observations in the submillimetre show that these QSOs are embedd…
The detection of Broad Iron K and L line emission in the Narrow-Line Seyfert 1 Galaxy 1H0707-495 using XMM-Newton
A. C. Fabian, A. Zoghbi, R. R. Ross +14
Since the discovery of the first broad iron-K line in 1995 from the Seyfert Galaxy MCG--6-30-15, broad iron-K lines have been found in several other Seyfert galaxies, from accretin…
