Fossil Groups Origins III. Characterization of the sample and observational properties of fossil systems
S. Zarattini, R. Barrena, M. Girardi +15
(Abridged) Fossil systems are group- or cluster-sized objects whose luminosity is dominated by a very massive central galaxy. In the current cold dark matter scenario, these object…
X-ray observations of the Compton-thick Seyfert 2 galaxy, NGC 5643
G. Matt, S. Bianchi, A. Marinucci +3
We present results from a ~55 ks long XMM-Newton observation of the obscured AGN, NGC 5643, performed in July 2009. A previous, shorter (about 10 ks) XMM-Newton observation in Febr…
How complex is the obscuration in AGN? New clues from the Suzaku monitoring of the X-ray absorbers in NGC7582
Stefano Bianchi, Enrico Piconcelli, Marco Chiaberge +3
We present the results of a Suzaku monitoring campaign of the Seyfert 2 galaxy, NGC7582. The source is characterized by very rapid (on timescales even lower than a day) changes of…
A BLR origin for the iron K line in NGC7213
Stefano Bianchi, Fabio La Franca, Giorgio Matt +5
The X-ray spectrum of NGC7213 is known to present no evidence for Compton reflection, a unique result among bright Seyfert 1s. The observed neutral iron K line, therefore, canno…
