Modeling Warm Absorption in HST/COS Spectrum of Mrk 290 with XSTAR
S. N. Zhang, L. Ji, T. R. Kallman +4
We present a new method to model a HST/COS spectrum, aimed to analyze intrinsic UV absorption from the outflow of Mrk 290, a Seyfert I galaxy. We use newly updated XSTAR to generat…

Anatomy of the AGN in NGC 5548: II. The Spatial, Temporal and Physical Nature of the Outflow from HST/COS Observations
N. Arav, C. Chamberlain, G. A. Kriss +30
(Abridged) Our deep multiwavelength campaign on NGC 5548 revealed an unusually strong X-ray obscuration. The resulting dramatic decrease in incident ionizing flux allowed us to con…

A fast and long-lived outflow from the supermassive black hole in NGC 5548
J. S. Kaastra, G. A. Kriss, M. Cappi +31
Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…
