Multiwavelength campaign on Mrk 509 XV. A global modeling of the broad emission lines in the Optical, UV and X-ray bands
E. Costantini, G. Kriss, J. S. Kaastra +11
We model the broad emission lines present in the optical, UV and X-ray spectra of Mrk 509, a bright type 1 Seyfert galaxy. The broad lines were simultaneously observed during a lar…
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…
