ZTF Bright Transient Survey classifications with APO (2020suj, taz, shr, and skb)
Keywords: Supernova
Abstract:
We announce classifications of supernovae 2020suj (Ia), 2020taz (Ibn), 2020shr (Ia), and 2020skb (Ia) with optical spectroscopy from Apache Point Observatory.
The Zwicky Transient Facility (ZTF; ATel #11266) Bright Transient Survey (BTS; ATel #11688; see also Fremling et al. 2019, arXiv:1910.12973) reports spectral classifications obtained with the Dual Imaging Spectrograph (range 340-1000nm, spectral resolution R~1000) mounted on the 3.5m telescope at Apache Point Observatory, and reduced with PyDIS (Davenport et al. 2016, http://doi.org/10.5281/zenodo.58753). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) or GELATO (Harutyunyan et al., 2008, A&A, 488, 383). All of the following classifications have been reported to the TNS and the spectra are publicly available.
2020suj and 2020skb were first reported by ATLAS; 2020taz by Pan-STARRS1; and 2020shr by ALeRCE.
