The Most Energetic Transients: Tidal Disruptions of High-Mass Stars
Jason T. Hinkle, Benjamin J. Shappee, Katie Auchettl +13
We present the class of extreme nuclear transients (ENTs), including the most energetic single transient yet discovered, Gaia18cdj. Each ENT is coincident with its host-galaxy nucl…
On the Double: Two Luminous Flares from the Nearby Tidal Disruption Event ASASSN-22ci (AT2022dbl) and Connections to Repeating TDE Candidates
Jason T. Hinkle, Katie Auchettl, Willem B. Hoogendam +16
We present observations of ASASSN-22ci (AT2022dbl), a nearby tidal disruption event (TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance of d$_L…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Discovery and Follow-up of ASASSN-23bd (AT 2023clx): The Lowest Redshift and Least Luminous Tidal Disruption Event To Date
W. B. Hoogendam, J. T. Hinkle, B. J. Shappee +23
We report the All-Sky Automated Survey for SuperNovae discovery of the tidal disruption event (TDE) ASASSN-23bd (AT 2023clx) in NGC 3799, a LINER galaxy with no evidence of strong…
TESS Shines Light on the Origin of the Ambiguous Nuclear Transient ASASSN-18el
Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee +11
We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASA…
Coronal Line Emitters are Tidal Disruption Events in Gas-Rich Environments
Jason T. Hinkle, Benjamin J. Shappee, Thomas W. -S. Holoien
Some galaxies show little to no sign of active galactic nucleus (AGN) activity, yet exhibit strong coronal emission lines (CLs) relative to common narrow emission lines. Many of th…
