SN2025aico: An Interesting Case Of Ni Mixing, Ejecta Asymmetries, and Dust Formation in a Type IIb Supernova
Grace Davis, Kyle Medler, Chris Ashall +8
Stripped-envelope supernovae provide a window into how massive stars lose their layers, mix radioactive material, produce dust, and explode asymmetrically. We present optical, near…
Little Red Dots as Shock-Powered High-Energy Neutrino Sources
Tyco Mera, Chris Ashall, Shunsaku Horiuchi +3
Little Red Dots (LRDs) are compact, high-redshift sources whose physical nature remains uncertain. Their optical spectra bear many similarities to Type IIn supernovae (SNe IIn), mo…
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…
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 durin…
JWST NIRSpec+MIRI Observations of the nearby Type IIP supernova 2022acko
M. Shahbandeh, C. Ashall, P. Hoeflich +65
We present JWST spectral and photometric observations of the Type IIP supernova (SN) 2022acko at ~50 days past explosion. These data are the first JWST spectral observations of a c…
Type Ia Supernova Progenitor Properties and Their Host Galaxies
Sudeshna Chakraborty, Benjamin Sadler, Peter Hoeflich +16
We present an eigenfunction method to analyze 161 visual light curves (LCs) of Type Ia supernovae (SNe Ia) obtained by the Carnegie Supernova Project to characterize their diversit…
