SuperNova IDentification spectral templates of 70 stripped-envelope core-collapse supernovae

Abstract

We constructed 70 SuperNova IDentification (SNID; Blondin & Tonry 2007) supernova (SN) templates using 640 spectra of stripped-envelope core-collapse SNe (SESNe) published by Modjaz et al. (2014). Fifty-six SN templates which are constructed from 458 spectra are brand new, increasing the number of SESNe and the number of SESNe spectra in the current SNID database by a factor of 2.6 and 2.0, respectively. We also made some type and phase refinements to templates in the current SNID database.

5 pages, 5 tables. Our SNID templates can be downloaded via our SNYU webpage (http://cosmo.nyu.edu/SNYU/spectra)
