VAR-PZnn: A machine-learning framework for AGN photometric redshifts using color and variability-based features

S. Satheesh-Sheeba, P. Sánchez-Sáez, R. J. Assef +39

Photometric redshift estimation for active galactic nuclei (AGNs) remains a fundamental challenge for current and upcoming large-scale photometric surveys. Traditional spectral ene…

VAR-PZ: Constraining the Photometric Redshifts of Quasars using Variability

S. Satheesh-Sheeba, R. J. Assef, T. Anguita +33

The Vera C. Rubin Observatory LSST is expected to discover tens of millions of new Active Galactic Nuclei (AGNs). The survey's exceptional cadence and sensitivity will enable UV/op…

Radio-Near Infrared Imaging of Dual Active Galactic Nuclei Candidates

Makoto A. Johnstone, Ilsang Yoon, Emmanuel Momjian +13

We report the results of a pilot study that searched for dual active galactic nuclei (AGN) in local (0.25) galaxies hosting double-peaked narrow emission lines in their optical…

Scalable and Robust Multiband Modeling of AGN Light Curves in Rubin-LSST

Weixiang Yu, John J. Ruan, Colin J. Burke +22

The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will monitor tens of millions of active galactic nuclei (AGNs) for a period of 10 years with an average caden…
