Classification of supernovae with LDSS-3
Authors: Emilio Hueichapan (UDP), Regis Cartier (UA), José Prieto (UDP)
Abstract:
This report includes the classification of 2 Type Ia and 1 Type II Supernovae.

We report the following supernova classifications.

Targets were supplied by the ATLAS survey (Smith et al. 2020 2020PASP..132h5002S), the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B) - data stream processed through the ALeRCE broker (Forster et al. 2020 2021AJ....161..242F) and by the ESA Gaia Photometric Science Alerts Team DPAC.

Observations were performed on the Clay Telescope at Las Campanas Observatory on the night of 2025 June 5, using LDSS-3 spectrograph providing a wavelength coverage of 3800-10,000 A. Classifications were performed using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) and GELATO (Harutyunyan et al. 2008 2008A&A...488..383H).
