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…
ATLAS22kjn (AT 2022fpx): A Coronal Line Emitter with an Early Light Curve Bump and Mid-Infrared Dust Echo
Athena C. Engholm, Jason T. Hinkle, Benjamin J. Shappee +14
We present an analysis of ATLAS22kjn (AT 2022fpx), whose high-ionisation coronal lines (CLs) and pre-peak light curve bump provide distinctive opportunities to investigate the phys…
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…
Comparison of X-ray Emission Properties of TDEs and Soft Flares from AGNs
Samaresh Mondal, K. Decker French, Jason T. Hinkle
X-ray flaring activity from active galactic nuclei (AGNs) may mimic the expected emission from tidal disruption events (TDEs), thus contaminating TDE searches. To compare X-ray emi…
Tracing Radio AGN-Driven Quenching in Post-Starburst Galaxies at Cosmic Noon
Pallavi Patil, Kate Rowlands, Katherine Alatalo +14
We present a radio continuum study of photometrically selected cosmic noon (0.5<z<3) post-starburst galaxies (PSBs) in the UKIDSS Deep Survey (UDS) field to assess if radio-mode Ac…
