Abstract:
We report spectroscopic classifications of three SNe-Ia and one 91T-like event.
The Young Supernova Experiment  (YSE; Jones et al. 2021 2021ApJ...908..143J), reports the following supernova classifications.  Targets were supplied by the Young Supernova Experiment, the ATLAS survey (Smith et al. 2020 2020arXiv200309052S) and by the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B).  Observations were performed on the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope on the night of 18/04/2021. Classifications were performed using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B)  and Superfit (Howell et al. 2005 2005ApJ...634.1190H).
