Variable X-ray absorption in the mini-broad absorption line quasar PG 1126-041
Margherita Giustini, Massimo Cappi, George Chartas +7
We present the results of a multi-epoch observational campaign on the mini-broad absorption line quasar (mini-BAL QSO) PG 1126-041 performed with XMM-Newton from 2004 to 2009. Time…
Jets and outflows in Radio Galaxies: implications for AGN feedback
E. Torresi, P. Grandi, E. Costantini +1
One of the main debated astrophysical problems is the role of the AGN feedback in galaxy formation. It is known that massive black holes have a profound effect on the formation and…
Variable X-ray absorption in the mini-BAL QSO PG 1126-041
Margherita Giustini, Massimo Cappi, George Chartas +7
X-ray studies of active galactic nuclei (AGN) with powerful nuclear winds are important for constraining the physics of the inner accretion/ejection flow around supermassive black…
Warm Absorber Energetics in Broad Line Radio Galaxies
E. Torresi, P. Grandi, E. Costantini +1
We review the soft X-ray properties of 3C 390.3, 3C 120, 3C 382 and 3C 445, the only Broad Line Radio Galaxies (BLRG) for which good quality gratings data are currently available.…
Evidence for ultra-fast outflows in radio-quiet AGNs: I - detection and statistical incidence of Fe K-shell absorption lines
F. Tombesi, M. Cappi, J. N. Reeves +4
We performed a blind search for narrow absorption features at energies greater than 6.4 keV in a sample of 42 radio-quiet AGNs observed with XMM-Newton. We detect 36 narrow absorpt…
A deep look at the inner regions of the mini-BAL QSO PG 1126-041 with XMM-Newton
M. Giustini, M. Cappi, G. Chartas +3
A long XMM-Newton observation of the mini-BAL QSO PG 1126-041 allowed us to detect a highly ionized phase of X-ray absorbing gas outflowing at v~15000 km/s. Physical implications a…
