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…

A JWST Medium Resolution MIRI Spectrum and Models of the Type Ia supernova 2021aefx at +415 d

C. Ashall, P. Hoeflich, E. Baron +39

We present a JWST MIRI/MRS spectrum (5-27 m) of the Type Ia supernova (SN Ia), SN 2021aefx at days past -band maximum. The spectrum, which was obtained during…
