The NuSTAR X-ray spectrum of the low-luminosity AGN in NGC 7213
F. Ursini, A. Marinucci, G. Matt +11
We present an analysis of the 3-79 keV NuSTAR spectrum of the low-luminosity active galactic nucleus NGC 7213. In agreement with past observations, we find a lower limit to the hig…
Anatomy of the AGN in NGC 5548 IV. The short-term variability of the outflows
L. Di Gesu, E. Costantini, J. Ebrero +16
During an extensive multiwavelength campaign that we performed in 2013-14 the prototypical Seyfert 1 galaxy NGC 5548 has been found in an unusual condition of heavy and persistent…
Anatomy of the AGN in NGC 5548: III. The high-energy view with NuSTAR and INTEGRAL
F. Ursini, R. Boissay, P. -O. Petrucci +15
We describe the analysis of the seven broad-band X-ray continuum observations of the archetypal Seyfert 1 galaxy NGC 5548 that were obtained with XMM-Newton or Chandra, simultaneou…
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…
