The Delay Time Distribution of Quasi-Periodic Eruptions
Margaret Shepherd, K. Decker French, Jason T. Hinkle +4
Quasi-periodic eruptions (QPEs) are quasi-periodic X-ray bursts observed in the nucleus of a galaxy. Multiple pieces of observational evidence link QPEs to tidal disruption events…
NAPTIME: A Neural-Process Framework for Rubin Alert Classification
Nicholas Earl, Siddharth Chaini, K. Decker French +3
The Vera C. Rubin Observatory Legacy Survey of Space and Time will produce a high-volume stream of irregularly sampled multiband alerts for which spectroscopic confirmation will be…
FEADME: Fast Elliptical Accretion Disk Modeling Engine
Nicholas Earl, K. Decker French, Jason T. Hinkle +5
We present FEADME (Fast Elliptical Accretion Disk Modeling Engine), a GPU-accelerated Python framework for modeling broad Balmer-line emission using a relativistic elliptical accre…
Identifying Changing-Look AGN Transitions in Light Curve Data with the Zwicky Transient Facility
Margaret E. Verrico, K. Decker French, Vivienne F. Baldassare +10
Changing-Look AGN (CL-AGN) are AGN which transition between Seyfert types, challenging AGN unification models. Most CL-AGN have been identified via repeat spectroscopy, making it d…
The Delay Time Distribution of Tidal Disruption Events
Margaret Shepherd, K. Decker French, Nicholas C. Stone +6
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of…
Radio Variability in Recently-Quenched Galaxies: The Impact of TDE or AGN Driven Outflows
K. Decker French, Kristina Nyland, Pallavi Patil +7
Outflows and jets launched from the nuclei of galaxies emit radio synchrotron emission that can be used to study the impact of accretion energy on the host galaxy. The decades-long…
