The evolution of the warm absorber reveals a shocked outflow in the narrow line Seyfert 1 galaxy IRAS 17020+4544
Mario Sanfrutos, Anna Lia Longinotti, Yair Krongold +2
We present the analysis of grating spectra of the Narrow Line Seyfert 1 Galaxy IRAS 17020+4544 observed by XMM-Newton in 2004 and 2014. In a previous work on these data, we reporte…
Spectral and polarimetric signatures of X-ray eclipses in AGN
E. S. Kammoun, F. Marin, M. Dovciak +3
X-ray observations of active galactic nuclei (AGN) show variability on timescales ranging from a few hours up to a few days. Some of this variability may be associated with occulta…
Probing relativistic effects in the central engine of AGN
Mario Sanfrutos, Giovanni Miniutti
Active Galactic Nuclei (AGN) are perfect laboratories to check General Relativity (GR) effects by using Broad Line Region (BLR) clouds eclipses to probe the innermost regions of th…
The ionised X-ray outflowing torus in ESO 323-G77: low-ionisation clumps confined by homogeneous warm absorbers
Mario Sanfrutos, Giovanni Miniutti, Yair Krongold +2
We report on the long- and short-term X-ray spectral analysis of the polar-scattered Seyfert 1.2 galaxy ESO 323-G77, observed in three epochs between 2006 and 2013 with Chandra and…
Eclipsing the innermost X-ray emitting regions in AGN
Mario Sanfrutos, Giovanni Miniutti, Michal Dovčiak +1
Variable X-ray absorption has been observed in active galactic nuclei (AGN) on several time scales. Observations allow us to identify the absorber with clouds associated either wit…
