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…
Radio constraints on the volume filling factors of AGN winds
A. J. Blustin, A. C. Fabian
The calculation of mass outflow rates of AGN winds is of great importance in understanding the role that such winds play in AGN-galaxy feedback processes. The mass outflow rates ar…
