Supernova Rates and Luminosity Functions from ASAS-SN III: Over a Decade of Type Ia SNe and Their Subtypes
Dhvanil D. Desai, Benjamin J. Shappee, Christopher S. Kochanek +11
We present volumetric rates and luminosity functions (LFs) of Type Ia supernovae (SNe Ia) from the All-Sky Automated Survey for Supernovae (ASAS-SN), covering the 11-year period fr…
Post-Perihelion Integral Field Spectroscopy of the Interstellar Comet 3I/ATLAS
Willem B. Hoogendam, David O. Jones, Bin Yang +10
The environs of other stellar systems may be directly probed by analyzing the cometary activity of interstellar objects. The recently discovered interstellar object 3I/ATLAS was th…
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…
Plasma Instabilities Dominate Radioactive Transients Magnetic Fields: The self-confinement of leptons in Type Ia and Core-Collapse Supernovae, and Kilonovae
Dhvanil D. Desai, Colby C. Haggerty, Benjamin J. Shappee +8
The light curves of radioactive transients, such as supernovae and kilonovae, are powered by the decay of radioisotopes, which release high-energy leptons through and d…
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…
