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…
Cosmic Pairs: A DESI Census of Dual and Offset AGN as Precursors to Massive Black Hole Binaries
Ekaterine Dadiani, Antonella Palmese, Yihao Zhou +52
The paper presents a large, uniformly selected spectroscopic catalog of dual and offset active galactic nuclei from the first DESI data release, analyzing their host galaxy propert…
Stacked Reverberation Mapping of High Redshift Quasars in DESI. I. Feasibility Analysis
Rahma Alfarsy, R. E. A. Canning, Eva-Maria Mueller +49
The broad line region of quasars has long been probed by reverberation mapping techniques that measure time lags between continuum and broad emission line variations. Stacked rever…
Beyond traditional emission-line diagnostics: using autoencoders to uncover active galactic nuclei in DESI spectra
J. A. Alcolea, M. Siudek, M. Eriksen +49
The growing volume of spectroscopic data in modern surveys motivates data-driven approaches that complement traditional emission-line diagnostics for active galactic nuclei (AGN) i…
The largest sample of AGN outflows in dwarf galaxies using DESI DR1
V. RodrÃguez Morales, M. Mezcua, Ragadeepika Pucha +40
In the last decade, the presence of active galactic nuclei (AGN) outflows and feedback in dwarf galaxies (<) has gained ground over supern…
A New Record Census of Dwarf AGN and a Bimodal - Scaling Relation with DESI DR1
Ragadeepika Pucha, S. Juneau, M. Mezcua +48
Using the first spectroscopic data release from the Dark Energy Spectroscopic Instrument (DESI DR1), we search for AGN signatures in 1,678,787 low-redshift ()…
