Testing warm Comptonization models for the origin of the soft X-ray excess in AGN
P. O. Petrucci, F. Ursini, A. De Rosa +5
The X-ray spectra of many active galactic nuclei (AGN) show a soft X-ray excess below 1-2 keV on top of the extrapolated high- energy power law. The origin of this component is unc…
NuSTAR spectral analysis of two bright Seyfert 1 galaxies: MCG +8-11-11 and NGC 6814
A. Tortosa, S. Bianchi, A. Marinucci +10
We report on the NuSTAR observations of two bright Seyfert 1 galaxies, namely MCG +8-11-11 (100 ks) and NGC 6814 (150 ks). The main goal of these observations was to investigate th…
A deep X-ray view of the bare AGN Ark120. IV. XMM-Newton and NuSTAR spectra dominated by two temperature (warm, hot) Comptonization processes
D. Porquet, J. N. Reeves, G. Matt +16
We perform an X-ray spectral analysis of the brightest and cleanest bare AGN known so far, Ark 120, in order to determine the process(es) at work in the vicinity of the SMBH. We pr…
Spatially resolved Fe K spectroscopy of NGC 4945
Andrea Marinucci, Stefano Bianchi, Giuseppina Fabbiano +4
We present the imaging and spectroscopic analysis of the combined Chandra ACIS-S observations of the Compton-thick Seyfert 2 galaxy NGC 4945. We performed a spatially-resolved spec…
Disentangling the Complex Broadband X-ray Spectrum of IRAS 13197-1627 with NuSTAR, XMM-Newton and Suzaku
D. J. Walton, M. Brightman, G. Risaliti +8
We present results from a coordinated -+ observation of the type 1.8 Seyfert galaxy IRAS 13197-1627. This is a highly complex source, with strong contributions…
A Long Look At MCG-5-23-16 With NuSTAR: I- Relativistic Reflection And Coronal Properties
Abderahmen Zoghbi, G. Matt, J. M. Miller +13
MCG-5-23-16 was targeted in early 2015 with a half mega-seconds observing campaign using NuSTAR. Here we present the spectral analysis of these datasets along with an earlier obser…
