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…

On unveiling Buried Nuclei with JWST: a technique for hunting the most obscured galaxy nuclei from local to high redshift
I. GarcÃa-Bernete, F. R. Donnan, D. Rigopoulou +12
We analyze JWST NIRSpec+MIRI/MRS observations of the infrared (IR) Polycyclic Aromatic Hydrocarbon (PAH) features in the central regions (0.26'' at 6 micron; 50-440 pc…
