The XMM-Newton Wide Angle Survey (XWAS)
P. Esquej, M. Page, F. J. Carrera +16
This programme is aimed at obtaining one of the largest X-ray selected samples of identified active galactic nuclei to date in order to characterise such a population at intermedia…
Accretion and outflow of gas in Markarian 509
Jelle Kaastra, Pierre-Olivier Petrucci, Massimo Cappi +13
A major uncertainty in models for photoionised outflows in AGN is the distance of the gas to the central black hole. We present the results of a massive multiwavelength monitoring…
Multiwavelength campaign on Mrk 509 VIII. Location of the X-ray absorber
J. S. Kaastra, R. G. Detmers, M. Mehdipour +14
The bright Seyfert 1 galaxy Mrk 509 was monitored by XMM-Newton and other satellites in 2009 to constrain the location of the outflow. We have studied the response of the photoioni…
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 VII. Relative abundances of the warm absorber
K. C. Steenbrugge, J. S. Kaastra, R. G. Detmers +14
Context. The study of abundances in the nucleus of active galaxies allows us to investigate the evolution of abundance by comparing local and higher redshift galaxies. However, the…
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…
