The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves
M. Kopsacheili, L. Galbany, G. Folatelli +32
We present observations of the 1991bg-like type Ia supernova (SN) 2023vjh, associated with the elliptical galaxy MCG+04-10-013. Its light-curve shape parameters ($Îm_{15}(B)=1.89…
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…
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…
The Enigmatic Type Icn Supernova 2024abvb Located ~22 kpc from Its Host Galaxy
J. Shi, K. Auchettl, W. B. Hoogendam +29
We report multiwavelength observations of the highly offset (~22.4 kpc) SN 2024abvb, the sixth Type Icn supernova to date. With a peak magnitude of Mr = -19.55 +/- 0.11 mag, it is…
JWST Observations of SN 2023ixf I: Completing the Early Multi-Wavelength Picture with Plateau-phase Spectroscopy
J. M. DerKacy, C. Ashall, E. Baron +46
We present and analyze panchromatic (0.35--14 m) spectroscopy of the Type II supernova 2023ixf, including near- and mid-infrared spectra obtained 33.6 days after explosion duri…
The Hawaii Infrared Supernova Study (HISS): Spectroscopic Data Release 1
K. Medler, C. Ashall, M. Shahbandeh +9
We present the first data release of the Hawaii Infrared Supernova Study (\textit{HISS}), consisting of a large sample of near-infrared (NIR) spectra, , obt…
