JWST Observations of SN 2023ixf II: The Panchromatic Evolution Between 250 and 720 Days After the Explosion
K. Medler, C. Ashall, P. Hoeflich +60
We present the nebular phase spectroscopic and photometric observations of the nearby hydrogen-rich core-collapse supernova (CC-SN) 2023ixf, obtained through our JWST programs. The…

Very Late-Time JWST and Keck Spectra of the Oxygen-Rich Supernova 1995N
Geoffrey C. Clayton, R. Wesson, Ori D. Fox +43
We present new {\it JWST}/MIRI MRS and Keck spectra of SN 1995N obtained in 2022--2023, more than 10,000 days after the supernova (SN) explosion. These spectra are among the latest…

JWST/MIRI detects the dusty SN1993J about 30 years after explosion
Tamás Szalai, Szanna Zsíros, Jacob Jencson +37
Core-collapse supernovae (CCSNe) have long been considered to contribute significantly to the cosmic dust budget. New dust cools quickly and is therefore detectable at mid-infrared…
