The host galaxies of 2003fg-like type Ia supernovae
Lluís Galbany, Chris Ashall, Jing Lu +19
SN~2003fg-like events are a peculiar type Ia supernova (SN~Ia) subtype characterized by broader light curves, higher near-infrared luminosities, and stronger carbon absorptions at…
Panchromatic JWST Observations and Models of the Dim Type Iax Supernova 2024vjm at 200 days
E Baron, J. M. DerKacy, C. Ashall +23
We report JWST spectra and photometry of the underluminous SN Iax 2024vjm obtained 202.8 restframe days post-explosion. The spectrum exhibits a rich set of forbidden lines from low…
The Production of Electron-Capture Elements in Thermonuclear Supernovae: Theory vs. Observations
S. Shiber, P. Hoeflich, T. Mera +9
Type Ia supernovae (SNe Ia) explosively destroy carbon-oxygen white dwarfs (WDs) in multiple stellar systems. They produce approximately 50% of the iron-group elements in the Unive…
JWST Medium-Resolution Infrared Spectroscopy of SN 2022acko: Tracing Molecule Formation in the Nebular Phase
K. Medler, T. Mera, C. Ashall +28
The Type II supernova (SN II) SN 2022acko was the first to be spectroscopically observed by the James Webb Space Telescope (). Here, we analyze SN 2022acko's second…
SN 2019vxm: A luminous and long-lived Type IIn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, T. J. Moriya +38
We present the photometric and spectroscopic analysis of the luminous and long-lasting Type IIn supernova (SN) 2019vxm. The SN reaches a peak V-band absolute magnitude of MV = -20.…
Probing the 3D Structures of Supernovae through IR Signatures of CO and SiO
T. Mera, P. Hoeflich, C. R. Burns +12
We present a new public-domain MOlecular Fitting Analysis Tool (MOFAT) designed to probe molecule-forming regions in supernovae (SNe) through analysis of molecular features in the…
