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…
Predictions of Transiting Exoplanet Confirmations from Rubin LSST Surveys
Suber Corley, Eric Feigelson, Claudio Caceres +2
We assess the prospects for exoplanet transit observations in the 10-year Wide Fast Deep (WFD) and Deep Drilling Field (DDF) surveys within the Legacy Survey of Space and Time (LSS…
A Meta-Learning Framework for Multitask Reverberation Mapping in Active Galactic Nuclei
Aman N. Raju, Andjelka B. Kovačević, Andjelka B. KovaÄeviÄ +15
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) is expected to observe active galactic nuclei (AGN) at sky densities of approximately 1000-4000 per sq. deg, en…
Prospects for Astrobiology and Technosignature Searches with the Vera C. Rubin Observatory Legacy Survey of Space and Time
Andjelka B Kovacevic, Nigel J. Mason, Aleksandra Ciprijanovic +4
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will map sources in multiband colour--variability space. We present a prototype coherence-based framework for a…
AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817
John W. Montano, Aaron J. Barth, Keith Horne +40
We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…
