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…
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…
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 with a relativistic elliptical accret…
JWST and Keck Observations of the Off-Nuclear TDE AT 2024tvd: A Massive Nuclear Star Cluster and Minor-Merger Origin for its Black Hole
Kishore C. Patra, Ryan J. Foley, Nicholas Earl +10
We present JWST/NIRSpec and NIRCam observations of the first optically selected off-nuclear tidal disruption event (TDE), AT 2024tvd, along with Keck/KCWI integral field unit spect…
Utilizing Maximum Variability to Discern TDE Emission from AGN Flares
Samaresh Mondal, K. Decker French
X-ray emission arising from active galactic nucleus (AGN) activity may potentially mimic the expected emission of tidal disruption events (TDEs). Ongoing and upcoming wide-field X-…
The Double Tidal Disruption Event AT 2022dbl Implies That at Least Some "Standard" Optical TDEs are Partial Disruptions
Lydia Makrygianni, Iair Arcavi, Megan Newsome +37
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of ac…
AT 2020nov: Evidence for Disk Reprocessing in a Rare Tidal Disruption Event
Nicholas Earl, K. Decker French, Enrico Ramirez-Ruiz +23
We present a detailed analysis of AT 2020nov, a tidal disruption event (TDE) in the center of its host galaxy, located at a redshift of . AT 2020nov exhibits unique feat…
Quasi-periodic X-ray eruptions and tidal disruption events prefer similar host galaxies
T. Wevers, K. D. French, A. I. Zabludoff +10
In the past five years, six quasi-periodic X-ray eruption (QPE) sources have been discovered in the nuclei of nearby galaxies. Their origin remains an open question. We present MUS…
Light-Curve Structure and Halpha Line Formation in the Tidal Disruption Event AT 2019azh
Sara Faris, Iair Arcavi, Lydia Makrygianni +33
AT 2019azh is a H+He tidal disruption event (TDE) with one of the most extensive ultraviolet and optical data sets available to date. We present our photometric and spectroscopic o…
