The X-ray-to-UV relation does not evolve in homogeneous quasar samples

G. Risaliti, E. Lusso, E. Nardini +6

We present a new, highly homogeneous quasar sample with X-ray and UV observations optimized to reliably estimate distances via the non-linear X-ray-to-UV relation. Cross-matching t…

Is XRISM/Resolve probing a "raining" absorber in Mrk 509?

M. Dadina, V. Missaglia, V. Braito +19

X-ray spectroscopy of AGN offers unique insights into the reprocessing of radiationand gas dynamics near SMBH. The Sey 1 galaxy Mrk 509 is an ideal laboratory for these studies sin…

Ultra-thick warm absorbers: Enlarging the parameter space of AGN ionised outflows

R. Middei, E. Piconcelli, E. Nardini +9

The analysis of X-ray absorption features in active galactic nuclei (AGN) provides a wealth of information about the physical properties of the matter surrounding supermassive blac…

Supermassive Black Hole Winds in X-rays: SUBWAYS V. Properties of hot coronae in quasars at intermediate redshift

S. Peluso, G. Lanzuisi, A. Comastri +25

We present the X-ray analysis of coronal properties in a statistically representative sample of 23 mostly radio-quiet AGN from the SUBWAYS campaign (SUpermassive Black holes Winds…

Constraining black hole spin in PG 1535+547 amidst complex multi-layered absorption

A. Madathil-Pottayil, D. J. Walton, Jiachen Jiang +7

We present a spectroscopic analysis of XMM-Newton and NuSTAR observations of the 'complex' NLS1 PG 1535+547 at redshift . These observations span three epochs: 2002 and 20…
