JWST Spectroscopy of SN Ia 2022aaiq and 2024gy: Evidence for Enhanced Central Stable Ni Abundance and a Deflagration-to-Detonation Transition

Lindsey A. Kwok, Chang Liu, Saurabh W. Jha +48

We present optical + near-infrared (NIR) + mid-infrared (MIR) observations of the normal Type Ia supernovae (SN Ia) 2022aaiq and 2024gy in the nebular phase, continuously spanning…

The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time NIR Spectroscopy from the Carnegie Supernova Project-II

Sahana Kumar, Eric Y. Hsiao, Christopher Ashall +20

Producing stable Ni in Type Ia supernovae (SNe Ia) requires sufficiently high density conditions that are not predicted for all origin scenarios, so examining the distributi…

Peaky Finders: Characterizing Double-Peaked Type IIb Supernovae in Large-Scale Live-Stream Photometric Surveys

Adrian Crawford, Tyler A. Pritchard, Maryam Modjaz +3

We present the first photometric population study of double-peaked Type IIb supernovae (SNe IIb). SNe IIb are produced from the core-collapse of massive stars whose outermost Hydro…
