A deep X-ray view of the bare AGN Ark 120. VI. Geometry of the hot corona from spectroscopic and polarization signatures
A. Marinucci, D. Porquet, F. Tamborra +9
The spectral shape of the hard X-ray continuum of Active Galactic Nuclei (AGN) can be ascribed to inverse Compton scattering of optical/UV seed photons from the accretion disc by a…
Towards an informed quest for accretion disc winds in quasars: the intriguing case of Ton 28
Emanuele Nardini, Elisabeta Lusso, Susanna Bisogni
We report on the detection of a blueshifted Fe K absorption feature in two consecutive XMM-Newton observations of the luminous blue quasar Ton 28, at the 4 cumulative significan…
Resolving the X-ray obscuration in a low flux observation of the quasar PDS 456
James Reeves, Valentina Braito, Emanuele Nardini +5
Simultaneous XMM-Newton, NuSTAR and HST observations, performed in March 2017, of the nearby () luminous quasar PDS 456 are presented. PDS 456 had a low X-ray flux compare…
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…
Tracking the Iron K line and the Ultra Fast Outflow in NGC 2992 at different accretion states
A. Marinucci, S. Bianchi, V. Braito +3
The Seyfert 2 galaxy NGC 2992 has been monitored eight times by XMM-Newton in 2010 and then observed again in 2013, while in 2015 it was simultaneously targeted by Swift and NuSTAR…
Testing the accuracy of reflection-based supermassive black hole spin measurements in AGN
E. S. Kammoun, E. Nardini, G. Risaliti
X-ray reflection is a very powerful method to assess the spin of supermassive black holes (SMBHs) in active galactic nuclei (AGN), yet this technique is not universally accepted. I…
