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…
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…
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…
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 t…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
Spectral Models for Early Time SN 2011fe Observations
E. Baron, P. Hoeflich Brian Friesen, M. Sullivan +11
We use observed UV through near IR spectra to examine whether SN 2011fe can be understood in the framework of Branch-normal SNe Ia and to examine its individual peculiarities. As a…
A Physical Model for SN 2001ay, a normal, bright, extremely slowly declining Type Ia supernova
E. Baron, P. Hoeflich, K. Krisciunas +5
We present a study of the peculiar Type Ia supernova 2001ay (SN 2001ay). The defining features of its peculiarity are: high velocity, broad lines, and a fast rising light curve, co…
VLT Spectropolarimetry of the fast expanding Type Ia SN2006X
F. Patat, D. Baade, P. Hoeflich +3
Using VLT-FORS1 we performed optical spectropolarimetric observations of the Type Ia SN2006X on 7 pre-maximum epochs (day -10 to day -1) and one post-maximum epoch (+39 days). The…
