Feature-driven anomaly flagging in obscured active galactic nucleus light curves with autoencoders

Natale De Bonis, Demetra De Cicco, Stefano Cavuoti +5

Active galactic nuclei (AGN) are among the most complex classes of astrophysical objects, displaying a wide range of variability and observational properties. Identifying unusual A…

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…

AGILE: an end-to-end Rubin-LSST simulation of AGNs, galaxies, and stars I. Software description and first data release

A. Viitanen, A. Bongiorno, I. Saccheo +37

Contemporary large-scale surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) and Euclid present an unprecedented discovery potential for studying A…

AGN in massive galaxies identified via optical broadband variability: lessons from VST-COSMOS for future LSST science

B. Bichang'a, D. De Cicco, S. Kaviraj +4

We study the properties of 56 massive (M > 10 M) galaxies at that host AGN, detected via their broadband optical variability in the VST-COSMOS…

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…

Variability-selected AGN in dwarf galaxies: the incidence of AGN in dwarf and massive galaxies is similar

S. Kaviraj, D. De Cicco, I. Lazar +4

We use the VST-COSMOS survey to identify, via their optical broadband variability, 30 AGN in nearby (z<0.4) dwarf (10^8 MSun < M < 10^10 MSun) galaxies. VST-COSMOS offers a 1 deg^2…
