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 2024ggi I: Interpretation and Model Comparison of the Type II Supernova 2024ggi at 55 days Past Explosion
E. Baron, C. Ashall, J. M. DerKacy +40
We present panchromatic 0.4-21 microns observations of the nearby (about 7.2 Mpc) Type II supernova 2024ggi, obtained during the plateau phase at about 55 d past explosion. Our dat…
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…
Measuring Type Ia Supernova Angular-Diameter Distances with Intensity Interferometry
A. G. Kim, P. E. Nugent, Xingzhuo Chen +2
This paper investigates the potential of intensity interferometry, based on the Hanbury Brown-Twiss effect, for measuring supernova sizes and distances. Through optimized telescope…
Three-dimensional Structure of Incomplete Carbon-Oxygen Detonations in Type Ia Supernovae
A. Khokhlov, I. Dominguez, A. Y. Chtchelkanova +6
Carbon-oxygen (CO) detonation with reactions terminating either after burning of C in the leading C + C reaction or after burning of C and O to S…
