High-energy monitoring of NGC 4593 II. Broadband spectral analysis: testing the two-corona model
R. Middei, S. Bianchi, P. -O. Petrucci +9
It is widely believed that the primary X-ray emission of AGN is due to the Comptonisation of optical-UV photons from a hot electron corona, while the origin of the 'soft-excess' is…
Photoionized emission and absorption features in the high-resolution X-ray spectra of NGC 3783
Junjie Mao, M. Mehdipour, J. S. Kaastra +14
Our Swift monitoring program triggered two joint XMM-Newton, NuSTAR and HST observations on 11 and 21 December 2016 targeting NGC 3783, as its soft X-ray continuum was heavily obsc…
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…
HST/COS observations of the newly discovered obscuring outflow in NGC 3783
G. A. Kriss, M. Mehdipour, J. S. Kaastra +24
To understand the nature of transient obscuring outflows in active galactic nuclei, we observed the Seyfert 1 galaxy NGC 3783 on two occasions in December 2016 triggered by Swift m…
The NuSTAR view of the Seyfert Galaxy HE 0436-4717
Riccardo Middei, Fausto Vagnetti, Francesco Tombesi +4
We present the multi epoch spectral analysis of HE 0436-4717, a bright Seyfert 1 galaxy serendipitously observed by the high energy satellite NuSTAR four times between December 201…
Radio/X-ray monitoring of the broad-line radio galaxy 3C 382. High-energy view with XMM-Newton and NuSTAR
F. Ursini, P. -O. Petrucci, G. Matt +14
We present the analysis of five joint XMM-Newton/NuSTAR observations, 20 ks each and separated by 12 days, of the broad-line radio galaxy 3C 382. The data were obtained as part of…
