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…

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 ()…

Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. IV. Broad Emission Line Evolution Sequence Among Hα, Mg II, and Hβ
Wei-Jian Guo, Victoria A. Fawcett, MaÅgorzata Siudek +15
From a parent catalog of 561 changing-look active galactic nuclei (CL-AGNs) identified by Guo et al. (2025), we investigate the evolutionary sequence of broad emission lines using…
