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…
Prospects for Measuring Black Hole Masses using TDEs with the Vera C. Rubin Observatory
K. Decker French, Brenna Mockler, Nicholas Earl +1
Tidal Disruption Events (TDEs) provide an opportunity to study supermassive black holes that are otherwise quiescent. The Vera C. Rubin Legacy Survey of Space and Time will be capa…
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…
A Large-Scale Search for Photometrically Variable AGNs in Dwarf Galaxies Using the Young Supernova Experiment
Alexander Messick, Vivienne Baldassare, David O. Jones +12
We conduct an analysis of over 60,000 dwarf galaxies (7<=log(M_*/M_\odot)<=10) in search of photometric variability indicative of active galactic nuclei (AGNs). Using data from the…
Fading AGN in Post-Starburst Galaxies
K. Decker French, Nicholas Earl, Annemarie B. Novack +4
The role of AGN in quenching galaxies and driving the evolution from star-forming to quiescent remains a key question in galaxy evolution. We present evidence from the Mapping Near…
