YSE Spectroscopic Classifications of Optical Transients with the NOT
Authors: C. R. Angus (DARK, U Copenhagen), C. Rojas-Bravo, R. J. Foley (UC Santa Cruz)
Source Group: YSE
We report spectroscopic classifications of 3 optical transients, including two SNe Ia and one SN IIb.
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 ALFOSC spectrograph on the Nordic Optical Telescope (NOT) telescope on the night of 03/04/2021. Classifications were performed using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) and superfit (Howell et al. 2005 2005ApJ...634.1190H).
