Predicting High-magnification Events in Microlensed Quasars in the Era of LSST using Recurrent Neural Networks
Joshua Fagin, Eric Paic, Favio Neira +6
Upcoming widefield surveys, such as the Rubin Observatory's Legacy Survey of Space and Time (LSST), will monitor thousands of strongly lensed quasars over a 10 yr period. Many of t…
Latent Stochastic Differential Equations for Modeling Quasar Variability and Inferring Black Hole Properties
Joshua Fagin, Ji Won Park, Henry Best +6
Quasars are bright and unobscured active galactic nuclei (AGN) thought to be powered by the accretion of matter around supermassive black holes at the centers of galaxies. The temp…
Evolution of Quasi-Periodic Eruptions in the post-TDE Accretion Disk Perturbed by an Orbiting Star
Martin Mondek, Michal ZajaÄek, Henry Best +3
Quasi-periodic eruptions (QPEs) are a recently discovered class of highly variable X-ray bursts originating in galactic nuclei. These high-amplitude bursts exhibit periodicity rang…
Revealing EMRI/IMRI candidates with quasiperiodic ultrafast outflows
Michal ZajaÄek, Petra Suková, VladimÃr Karas +7
The first detection of the quasiperiodic ultrafast outflow in the ASASSN-20qc system was reported by Pasham et al. (2024). The outflow is revealed in the soft X-ray spectra as an a…
Amoeba: An AGN Model of Optical Emissions Beyond steady-state Accretion discs
Henry Best, Matthew O'Dowd, Joshua Fagin +2
Active Galactic Nuclei (AGN) are objects located in the heart of galaxies which emit powerful and complex radiation across the electromagnetic spectrum. Understanding AGN has becom…
Resolving the Vicinity of Supermassive Black Holes with Gravitational Microlensing
Henry Best, Joshua Fagin, Georgios Vernardos +1
In the near future, wide field surveys will discover 1000's of new strongly lensed quasars, and these will be monitored with unprecedented cadence by the Legacy Survey of Space and…
