The rise and decline of a transient obscuration event in a moderately distant type-I quasar
A. Akylas, A. Georgakakis, E. Pouliasis +5
Outflows of ionised material, often dubbed warm absorbers (WAs), are common in nearby Seyferts but sparse in distant and more energetic quasars (QSOs). We present multi-epoch X-ray…
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…
Identification of low redshift groups and clusters of galaxies in the X-CLASS survey and the X-ray luminosity-temperature relation
Q. Moysan, F. Sarron, N. Clerc +16
Properties of the hot intracluster and intragroup medium are mostly set by the underlying gravitational potential well, although complex astrophysical processes at play during thei…
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…
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…
