The X-rayUV Luminosity Relation of eROSITA Quasars

Andrea Sacchi, Guido Risaliti, Matilde Signorini +3

The non-linear relation between the UV and X-ray luminosity in quasars has been studied for decades. However, as we lack a comprehensive model able to explain it, its investigation…

Explaining the UV to X-ray correlation in AGN within the framework of X-ray illumination of accretion discs

E. Kammoun, I. E. Papadakis, M. Dovčiak +3

It is established that the ultraviolet (UV) and X-ray emissions in active galactic nuclei (AGN) are tightly correlated. This correlation is observed both in low- and high-redshift…

Chandra Discovery of a Candidate Hyper-Luminous X-ray Source in MCG+11-11-032

Adi Foord, Francesca Civano, Julia M. Comerford +9

We present a multi-wavelength analysis of MCG+11-11-032, a nearby AGN with the unique classification of both a binary and a dual AGN candidate. With new Chandra observations we aim…

A radio, optical, UV and X-ray view of the enigmatic changing look Active Galactic Nucleus 1ES~1927+654 from its pre- to post-flare states

Sibasish Laha, Eileen Meyer, Agniva Roychowdhury +17

The nearby type-II AGN 1ES1927+654 went through a violent changing-look (CL) event beginning December 2017 during which the optical and UV fluxes increased by four magnitudes over…

The first broadband X-ray view of the narrow line Seyfert 1 Ton S180

G. A. Matzeu, E. Nardini, M. L. Parker +15

We present joint \textit{XMM-Newton} and \textit{NuSTAR} observations of the `bare' narrow line Seyfert 1 Ton S180 (), carried out in 2016 and providing the first hard X-r…
