Anatomy of the AGN in NGC 5548 VIII. XMM-Newton's EPIC detailed view of an unexpected variable multilayer absorber
M. Cappi, B. De Marco, G. Ponti +21
In 2013 we conducted a large multi-wavelength campaign on the archetypical Seyfert 1 galaxy NGC 5548. Unexpectedly, this usually unobscured source appeared strongly absorbed in the…
Anatomy of the AGN in NGC 5548: VII. Swift study of obscuration and broadband continuum variability
M. Mehdipour, J. S. Kaastra, G. A. Kriss +16
We present our investigation into the long-term variability of the X-ray obscuration and optical-UV-X-ray continuum in the Seyfert 1 galaxy NGC 5548. In 2013 and 2014, the Swift ob…
Anatomy of the AGN in NGC 5548. VI. Long-term variability of the warm absorber
J. Ebrero, J. S. Kaastra, G. A. Kriss +13
(Abridged) The archetypal Seyfert 1 galaxy NGC 5548 was observed in 2013-2014 in the context of an extensive multiwavelength campaign, which revealed the source to be in an extraor…
Anatomy of the AGN in NGC 5548: V. A clear view of the X-ray narrow emission lines
M. Whewell, G. Branduardi-Raymont, J. S. Kaastra +15
Context. Our consortium performed an extensive multi-wavelength campaign of the nearby Seyfert 1 galaxy NGC 5548 in 2013-14. The source appeared unusually heavily absorbed in the s…
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…
