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…
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…
Multiwavelength campaign on Mrk 509. XIII. Testing ionized-reflection models on Mrk 509
R. Boissay, S. Paltani, G. Ponti +12
Active Galactic Nuclei (AGN) are the most luminous persistent objects in the universe. An excess of X-ray emission below about 2 keV, called soft-excess, is very common in Type 1 A…
Multiwavelength study of Cygnus A IV. Proper motion and location of the nucleus
K. C. Steenbrugge, K. M. Blundell, S. Pyrzas
Context. Cygnus A, as the nearest powerful FR II radio galaxy, plays an important role in understanding jets and their impact on the surrounding intracluster medium. Aims. To expla…
Dust reverberation-mapping of the Seyfert 1 galaxy WPVS48
F. Pozo Nuñez, M. Haas, R. Chini +7
Using robotic telescopes of the Universitatssternwarte Bochum near Cerro Armazones in Chile, we monitored the z=0.0377 Seyfert 1 galaxy WPVS48 (2MASX J09594263-3112581) in the opti…
