Local Supermassive Black Holes and Relics of Active Galactic Nuclei
A. Marconi, G. Risaliti, R. Gilli +3
We summarize a study where we test the hypothesis that local black holes (BH) are relics of AGN activity. We compare the mass function of BHs in the local universe with that expect…
An Unveiling Event in the Type 2 AGN NGC4388: A Challenge for a Parsec Scale Absorber
Martin Elvis, G. Risaliti, F. Nicastro +3
We present two Rossi Xray Timing Explorer (RXTE) PCA observations of the type~2 Seyfert galaxy NGC 4388 caught in an unusual low X-ray absorption state. The observations were trigg…
A panchromatic view of AGN
G. Risaliti, M. Elvis
We review the continuum emission of Active Galactic Nuclei (AGN) over the entire electromagnetic spectrum. After a brief historical introduction, we describe the main spectral prop…
The XMM-Newton and BeppoSAX view of the Ultra Luminous Infrared Galaxy MKN 231
V. Braito, R. Della Ceca, E. Piconcelli +11
We discuss XMM-Newton and BeppoSAX observations of MKN 231, the lowest-redshift Broad Absorption Line (BAL) QSO known so far and one of the best-studied Ultra Luminous Infrared Gal…
