Multiwavelength campaign on Mrk 509 VI. HST/COS observations of the far-ultraviolet spectrum
(EDP Sciences, 2011-10)
We present medium-resolution (lambda/Delta lambda similar to 20 000) ultraviolet spectra covering the 1155-1760 angstrom spectral range of the Seyfert 1 galaxy Mrk 509 obtained using the Cosmic Origins Spectrograph (COS) ...
Multiwavelength campaign on Mrk 509 XI. Reverberation of the Fe K alpha line
(EDP Sciences, 2013-01)
Context. We report on a detailed study of the Fe K emission/absorption complex in the nearby, bright Seyfert 1 galaxy Mrk 509. The study is part of an extensive XMM-Newton monitoring consisting of 10 pointings (~60 ks each) ...
Multiwavelength campaign on Mrk 509 X. Lower limit on the distance of the absorber from HST COS and STIS spectroscopy
(EDP Sciences, 2012-08)
Aims. Active galactic nuclei (AGN) often show evidence of photoionized outflows. A major uncertainty in models for these outflows is the distance (R) to the gas from the central black hole. In this paper we use the HST/COS ...
