SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +16
We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…
The Eye of Sauron in SN 2025ngs: a Short-plateau Cousin of SN 1998S with Evidence for a Ring-like Circumstellar Medium
Conor L. Ransome, David J. Sand, K. Azalee Bostroem +35
Interacting supernovae probe the twilight years of massive stars, exhibiting signatures of interaction between the supernova ejecta and surrounding material expelled from the proge…
The fate of the failed supernova candidate M31-2014-DS1
Emma R. Beasor, Nathan Smith, Jeniveve Pearson +4
The fate of massive stars above 20M remains uncertain. Debate persists about whether they die as supernovae (SNe), or if they collapse directly into black holes (BHs) wit…
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…
Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
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…
Spectroscopy of AT 2016blu's recurring supernova impostor outbursts
Mojgan Aghakhanloo, Nathan Smith, Jennifer E. Andrews +7
We present spectra of the supernova (SN) impostor AT 2016blu spanning over a decade. This transient exhibits quasiperiodic outbursts with a 113 d period, likely triggered by…
The red supergiant progenitor luminosity problem
Emma R. Beasor, Nathan Smith, Jacob E. Jencson
Analysis of pre-explosion imaging has confirmed red supergiants (RSGs) as the progenitors to Type II-P supernovae (SNe). However, extracting the RSG's luminosity requires assumptio…
Deep JWST/NIRCam imaging of Supernova 1987A
Mikako Matsuura, M. Boyer, Richard G. Arendt +46
JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
A First Look with JWST Aperture Masking Interferometry (AMI): Resolving Circumstellar Dust around the Wolf-Rayet Binary WR 137 beyond the Rayleigh Limit
Ryan M. Lau, Matthew J. Hankins, Joel Sanchez-Bermudez +20
We present infrared aperture masking interferometry (AMI) observations of newly formed dust from the colliding winds of the massive binary system Wolf-Rayet (WR) 137 with JWST usin…
JWST NIRCam Observations of SN 1987A: Spitzer Comparison and Spectral Decomposition
Richard G. Arendt, Martha L. Boyer, Eli Dwek +24
JWST NIRCam observations at 1.5-4.5 m have provided broad and narrow band imaging of the evolving remnant of SN 1987A with unparalleled sensitivity and spatial resolution. Compa…
JWST reveals a luminous infrared source at the position of the failed supernova candidate N6946-BH1
Emma R. Beasor, Griffin Hosseinzadeh, Nathan Smith +4
N6946-BH1 is the first plausible candidate for a failed supernova (SN), a peculiar event in which a massive star disappears without the expected bright SN, accompanied by collapse…
