NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…
Relations between phenomenological and physical parameters in the hot coronae of AGNs computed with the MoCA code
R. Middei, S. Bianchi, A. Marinucci +4
The primary X-ray emission in active galactic nuclei (AGNs) is widely believed to be due to Comptonisation of the thermal radiation from the accretion disc in a corona of hot elect…
The X-ray Polarization Probe mission concept
Keith Jahoda, Henric Krawczynski, Fabian Kislat +100
The X-ray Polarization Probe (XPP) is a second generation X-ray polarimeter following up on the Imaging X-ray Polarimetry Explorer (IXPE). The XPP will offer true broadband polarim…
HST unveils a compact mildly relativistic Broad Line Region in the candidate true type 2 NGC 3147
Stefano Bianchi, Robert Antonucci, Alessandro Capetti +9
NGC 3147 has been considered the best case of a true type 2 AGN: an unobscured AGN, based on the unabsorbed compact X-ray continuum, which lacks a broad line region (BLR). However,…
Nustar Measurement Of Coronal Temperature In Two Luminous, High Redshift Qsos
G. Lanzuisi, R. Gilli, M. Cappi +13
X-ray emission from AGN is believed to be produced via Comptonization of optical/UV seed photons emitted by the accretion disk, up-scattered by hot electrons in a corona surroundin…
A deep X-ray view of the bare AGN Ark120. V. Spin determination from disc-Comptonisation efficiency method
D. Porquet, C. Done, J. N. Reeves +13
[Abridged] In our previous work on Ark 120, we found that its 2014 X-ray spectrum is dominated by Comptonisation, while the relativistic reflection emission only originates at tens…
