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…
Variable X-ray Absorption in mini-BAL QSOs
M. Giustini, M. Cappi, G. Chartas +3
We present the results of X-ray spectral analysis of two mini-BAL QSOs, PG 1126-041 and PG 1351+640, aimed at getting insights into the physics of quasar outflows. We find strong X…
Confirmation of and Variable Energy Injection by a Near-Relativistic Outflow in APM 08279+5255
G. Chartas, C. Saez, W. N. Brandt +2
We present results from multi-epoch spectral analysis of XMM-Newton and Chandra observations of the broad absorption line (BAL) quasar APM 08279+5255. Our analysis shows significan…
High Velocity Outflows in Narrow Absorption Line Quasars
G. Chartas, J. Charlton, M. Eracleous +6
The current paradigm for the AGN phenomenon is a central engine that consists of an inflow of material accreting in the form of a disk onto a supermassive black hole. Observations…
X-ray evidence for a mildly relativistic and variable outflow in the luminous Seyfert 1 galaxy Mrk509
M. Cappi, F. Tombesi, S. Bianchi +9
There is growing evidence for the presence of blueshifted Fe K absorption lines in a number of radio-quiet AGNs and QSOs. These may be fundamental to probe flow dynamics near super…
