Multi-wavelength campaign on NGC 7469 IV. The broad-band X-ray spectrum
R. Middei, S. Bianchi, M. Cappi +17
We conducted a multi-wavelength six-month campaign to observe the Seyfert galaxy NGC~7469, using the space-based observatories \textit{HST}, \textit{Swift}, \textit{XMM-Newton} and…
Anatomy of the AGN in NGC 5548 IX. Photoionized emission features in the soft X-ray spectra
Junjie Mao, J. S. Kaastra, M. Mehdipour +10
The X-ray narrow emission line region (NELR) of the archetypal Seyfert 1 galaxy NGC\,5548 has been interpreted as a single-phase photoionized plasma that is absorbed by some of the…
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…
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…
Simultaneous XMM-\textit{Newton} and HST-COS observation of 1H0419-577: II. Broadband spectral modeling of a variable Seyfert galaxy
L. Di Gesu, E. Costantini, E. Piconcelli +3
In this paper we present the longest exposure (97 ks) XMM-Newton EPIC-pn spectrum ever obtained for the Seyfert 1.5 galaxy 1H 0419-577. With the aim of explaining the broadband emi…
