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…
AT2021yky: A Fast-Rising Optical Transient with Evolving Broad Hydrogen Emission Consistent with an Ambiguous Nuclear Transient
Paarmita Pandey, Jason T. Hinkle, Christopher Kochanek +14
Nuclear transients are powerful probes of supermassive black hole properties, offering insight into black hole mass, accretion physics, and the structure of galactic nuclei. Among…
The Peculiar Growth of Structure: Validating Measurements from TITAN Type Ia Supernovae and the Uchuu Simulations
Mitchell Dixon, David O. Jones, Nicole E. Drakos +11
The growth rate of cosmic structure, parameterized by , is a fundamental test of CDM and general relativity. Using Type Ia supernova (SN Ia) peculiar velocities in conju…
Characterising the Standardisation Properties of Type Ia Supernovae in the z band with Hierarchical Bayesian Modelling
Erin E. Hayes, Suhail Dhawan, Kaisey S. Mandel +21
Type Ia supernovae (SNe Ia) are standardisable candles: their peak magnitudes can be corrected for correlations between light curve properties and their luminosities to precisely e…
Unraveling the Nature of the Nuclear Transient AT2020adpi
Paarmita Pandey, Jason Hinkle, Christopher Kochanek +13
Transient events associated with supermassive black holes provide rare opportunities to study accretion and the environments of supermassive black holes. We present a multiwaveleng…
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…
