Bulk Comptonization: new hints from the luminous blazar 4C+25.05
E. S. Kammoun, E. Nardini, G. Risaliti +3
Blazars are often characterized by a spectral break at soft X-rays, whose origin is still debated. While most sources show a flattening, some exhibit a blackbody-like soft excess w…
Evidence for a radiatively driven disc-wind in PDS 456?
G. A. Matzeu, J. N. Reeves, V. Braito +5
We present a newly discovered correlation between the wind outflow velocity and the X-ray luminosity in the luminous () nearby ()…
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…
Nuclear absorption and emission in the AGN merger NGC 6240: the hard X-ray view
Emanuele Nardini
We present the analysis of four NuSTAR observations of the luminous infrared galaxy merger NGC 6240, hosting a close pair of highly obscured active galactic nuclei (AGN). Over a pe…
A deep X-ray view of the bare AGN Ark 120. III. X-ray timing analysis and multiwavelength variability
Andrew Lobban, Delphine Porquet, James Reeves +3
We present the spectral/timing properties of the bare Seyfert galaxy Ark 120 through a deep ~420ks XMM-Newton campaign plus recent NuSTAR observations and a ~6-month Swift monitori…
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…
