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…
Multiwavelength campaign on Mrk 509. III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
R. G. Detmers, J. S. Kaastra, K. C. Steenbrugge +13
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized…
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…
