Fooled by mass? Recovering the relation of quasars from their X-ray variability
Matilde Signorini, Andrea Sacchi, Bartolomeo Trefoloni +7
We measure the relation between the X-ray photon index and the Eddington ratio in unobscured type-1 quasars, using as parent sample the cross-match of the SDSS DR16Q…
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…
The X-ray properties of the most luminous quasars with strong emission-line outflows
Anastasia Shlentsova, Bartolomeo Trefoloni, Matilde Signorini +7
Strong outflows from active galactic nuclei are frequently observed in objects with lower coronal X-ray luminosity. This intrinsic X-ray weakness is considered a requirement for th…
