Coronal properties of the luminous radio-quiet quasar QSO B2202209
E. S. Kammoun, G. Risaliti, D. Stern +8
We present an analysis of the joint - and observations of the radio-quiet quasar QSO B2202209. Using an optical observation from the Hale Telescope at the…
NuSTAR catches the unveiling nucleus of NGC 1068
A. Marinucci, S. Bianchi, G. Matt +15
We present a NuSTAR and XMM-Newton monitoring campaign in 2014/2015 of the Compton-thick Seyfert 2 galaxy, NGC 1068. During the August 2014 observation, we detect with NuSTAR a flu…
Suzaku observations of 'bare' active galactic nuclei
D. J. Walton, E. Nardini, A. C. Fabian +2
We present a X-ray spectral analysis of a large sample of 25 'bare' active galactic nuclei, sources with little or no complicating intrinsic absorption, observed with Suzaku. Our w…
A reflection origin for the soft and hard X-ray excess of Ark 120
E. Nardini, A. C. Fabian, R. C. Reis +1
Over the last few years several models have been proposed to interpret the widespread soft excess observed in the X-ray spectra of type 1 active galactic nuclei (AGN). In particula…
