Wavelength Dependences of the Optical/UV and X-ray Luminosity Correlations of Quasars
Chichuan Jin, Elisabeta Lusso, Martin Ward +2
The inter-band correlations between optical/UV and X-ray luminosities of active galactic nuclei (AGN) are important for understanding the disc-coronal connection, as well as using…
The lively accretion disc in NGC 2992. III. Tentative evidence of rapid Ultra Fast Outflow variability
Alfredo Luminari, Andrea Marinucci, Stefano Bianchi +8
We report on the 2019 XMM-Newton+NuSTAR monitoring campaign of the Seyfert galaxy NGC 2992, observed at one of its highest flux levels in the X-rays. The time-averaged spectra of t…
HYPerluminous quasars at the Epoch of ReionizatION (HYPERION). A new regime for the X-ray nuclear properties of the first quasars
L. Zappacosta, E. Piconcelli, F. Fiore +40
The existence of luminous quasars (QSO) at the Epoch of Reionization (EoR; i.e. z>6) powered by supermassive black holes (SMBH) with masses challenges models…
X-HESS: a large sample of highly accreting serendipitous AGN under the XMM-Newton microscope
M. Laurenti, F. Tombesi, F. Vagnetti +3
The bulk of X-ray spectroscopic studies of active galactic nuclei (AGN) are focused on local () sources with low-to-moderate () Eddington ratio ().…
Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
