1991T-like Supernovae
M. M. Phillips, C. Ashall, Peter J. Brown +23
Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In t…
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…
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…
