Revisiting the X-ray-to-UV relation of Quasars in the era of all-sky surveys
Maria Chira, Antonis Georgakakis, Angel Ruiz +8
The X-ray--to--UV relation of active galactic nuclei (AGNs), commonly parametrized via the monochromatic luminosities at and , reflects the energetic i…
Dependence on the environment of the abundance function of light-cone simulation dark matter haloes
Maria Chira, Manolis Plionis, Pier-Stefano Corasaniti
Aims.We study the dependence of the halo abundance function (AF) on different environments in a whole-sky CDM light-cone halo catalogue extending to z < 0.65, using a simple an…
CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength
Amy L. Rankine, David Homan, James Aird +25
We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between detected in the deepest Spec…
Dependence of the dynamical properties of light-cone simulation dark matter halos on their environment
Maria Chira, Manolis Plionis, Shankar Agarwal
Aims: We study the dependence of the dynamical properties of dark matter halos on their environment in a whole-sky CDM light-cone simulation extending to . The prop…
Host galaxy and orientation differences between AGN different types
Anamaria Gkini, Manolis Plionis, Maria Chira +1
Aims.The main purpose of this study is to investigate aspects regarding the validity of the active galactic nucleus (AGN) unification paradigm (UP). In particular, we focus on the…
Characterising the X-ray variability of QSOs to the highest Eddington ratios and black hole masses with eROSITA light curves
Antonis Georgakakis, Angel Ruiz, Johannes Buchner +9
An important diagnostic of the inner structure of accretion flows onto supermassive black holes are the stochastic flux variations at X-ray wavelengths. Despite its significance, a…
