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…
Calibration and in orbit performance of the reflection grating spectrometer onboard XMM-Newton
C. P. de Vries, J. W. den Herder, C. Gabriel +6
Context: XMM-Newton was launched on 10 December 1999 and has been operational since early 2000. One of the instruments onboard XMM-Newton is the reflection grating spectrometer (RG…
Multiwavelength campaign on Mrk 509 XIV. Chandra HETGS spectra
J. S. Kaastra, J. Ebrero, N. Arav +14
We present in this paper the results of a 270 ks Chandra HETGS observation in the context of a large multiwavelength campaign on the Seyfert galaxy Mrk 509. The HETGS spectrum allo…
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…
