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…

Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl

Yize Dong, V. Ashley Villar, Anya Nugent +35

In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…

Spatial Profiles of 3I/ATLAS CN and Ni Outgassing from Keck/KCWI Integral Field Spectroscopy

W. B. Hoogendam, B. J. Shappee, J. J. Wray +11

Cometary activity from interstellar objects provides a unique window into the environs of other stellar systems. We report blue-sensitive integral field unit spectroscopy of the in…

JWST Observations of SN 2024ggi II: NIRSpec Spectroscopy and CO Modeling at 285 and 385 Days Past the Explosion

T. Mera, C. Ashall, P. Hoeflich +20

We present James Webb Space Telescope (JWST) NIRSpec observations of SN~2024ggi, spanning wavelengths of 1.7--5.5 micron at +285.51 and +385.27 days post-explosion. These nebular s…

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…
