Magnetic White Dwarfs in the SDSS 100 pc Sample: Further Evidence of Two Formation Channels
Adam Moss, Mukremin Kilic, Pierre Bergeron +5
We conduct a model atmosphere analysis on all magnetic white dwarfs in the SDSS 100 pc sample. We have 163 magnetic targets in this sample, 87 of which are new discoveries, making…
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…
Optical Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Projects I and II
N. Morrell, M. M. Phillips, G. Folatelli +57
We present the second and final release of optical spectroscopy of Type Ia Supernovae (SNe Ia) obtained during the first and second phases of the Carnegie Supernova Project (CSP-I…
Extrapolation of Type Ia Supernova Spectra into the Near-Infrared Using PCA
Anthony Burrow, E. Baron, Christopher R. Burns +14
We present a method of extrapolating the spectroscopic behavior of Type Ia supernovae (SNe Ia) in the near-infrared (NIR) wavelength regime up to 2.30 m using optical spectrosco…
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…
JWST MIRI/MRS Observations and Spectral Models of the Under-luminous Type Ia Supernova 2022xkq
J. M. DerKacy, C. Ashall, P. Hoeflich +44
We present a JWST mid-infrared spectrum of the under-luminous Type Ia Supernova (SN Ia) 2022xkq, obtained with the medium-resolution spectrometer on the Mid-Infrared Instrument (MI…
Direct Analysis of the Broad-Line SN 2019ein: Connection with the Core-Normal SN 2011fe
Zach Yarbrough, E. Baron, James M. DerKacy +3
Type Ia supernovae (SNe Ia) are important cosmological probes and contributors to galactic nucleosynthesis, particularly of the iron group elements. To improve both their reliabili…
JWST Low-Resolution MIRI Spectral Observations of SN~2021aefx: High-density Burning in a Type Ia Supernova
J. M. DerKacy, C. Ashall, P. Hoeflich +38
We present a JWST/MIRI low-resolution mid-infrared (MIR) spectroscopic observation of the normal Type Ia supernova (SN Ia) SN 2021aefx at +323 days past rest-frame B-band maximum l…
Carnegie Supernova Project: Classification of Type Ia Supernovae
Anthony Burrow, E. Baron, Chris Ashall +14
We use the spectroscopy and homogeneous photometry of 97 Type Ia supernovae obtained by the \emph{Carnegie Supernova Project} as well as a subset of 36 Type Ia supernovae presented…
