X-ray absorption variability in NGC 4507
Andrea Marinucci, Guido Risaliti, Junfeng Wang +5
We present a complete spectral analysis of an XMM-Newton and Chandra campaign of the obscured AGN in NGC 4507, consisting of six observations spanning a period of six months, rangi…
Active galaxy 4U 1344-60: did the relativistic line disappear?
Jiri Svoboda, Stefano Bianchi, Matteo Guainazzi +4
X-ray bright active galactic nuclei represent a unique astrophysical laboratory for studying accretion physics around super-massive black holes. 4U 1344-60 is a bright Seyfert gala…
X-ray polarimetry as a new tool to discriminate reflection from absorption scenarios -- Predictions for MCG-6-30-15
F. Marin, R. W. Goosmann, M. Dovciak +5
We present modelling of X-ray polarisation spectra emerging from the two competing scenarios that are proposed to explain the broad Fe Kα line in the Seyfert 1 galaxy MCG-6-30-15.…
