Using nebular near-IR spectroscopy to measure asymmetric chemical distributions in 2003fg-like thermonuclear supernovae
J. O'Hora, C. Ashall, M. Shahbandeh +10
We present an analysis of three near-infrared (NIR; 1.0-2.4 m) spectra of the SN 2003fg-like/"super-Chandrasekhar" type Ia supernovae (SNe Ia) SN 2009dc, SN 2020hvf, and SN 2022…
The Redshift of GRB 190829A/ SN 2019oyw: A Case Study of GRB-SN Evolution
Kornpob Bhirombhakdi, Andrew S. Fruchter, Andrew J. Levan +7
The nearby long gamma-ray burst (GRB) 190829A was observed using the HST/WFC3/IR grisms about four weeks to 500 days after the burst. We find the spectral features of its associate…
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…
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…
