Black-hole masses of type 1 AGN in the XMM-Newton bright serendipitous survey
A. Caccianiga, R. Fanali, P. Severgnini +3
We derive masses of the central super-massive black hole (SMBH) and accretion rates for 154 type1 AGN belonging to a well-defined X-ray-selected sample, the XMM-Newton Serendipitou…
A new technique to efficiently select Compton-thick AGN
P. Severgnini, A. Caccianiga, R. Della Ceca
We present a new efficient diagnostic method, based on mid-infrared and X-ray data, to select local (z<0.1) Compton-thick (CT) AGN with the aim of estimating their surface and spac…
NGC454: unveiling a new "changing look" AGN
Elena Marchese, Valentina Braito, Roberto Della Ceca +2
We present a detailed analysis of the X-ray spectrum of the Seyfert 2 galaxy NGC454E, belonging to the interacting system NGC454. Observations performed with Suzaku, XMM-Newton and…
