The X-ray-Weak Tail of the Quasar Population: Physical Properties and Redshift Evolution of Variability-Selected AGN in eFEDS
P. Arévalo, J. Buchner, M. Salvato +10
The paper examines AGN identified through optical variability in the eROSITA eFEDS survey, comparing those detected in X‑rays to those that are not, and finds that a substantial hi…

Unlocking AGN Variability with Custom ZTF Photometry for High-Fidelity Light Curves and Robust Selection
P. Arévalo, P. Sánchez-Sáez, B. Sotomayor +3
(Abridged)We explore the potential of optical variability selection methods to identify AGN, including those challenging to detect with conventional techniques. Using the unprecede…
