ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.
Targets were supplied by the ATLAS survey (Smith et al. 2020 2020arXiv200309052S), the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B) - data stream processed through the Lasair broker (Smith, Williams, Young et al. 2019 2019RNAAS...3a..26S).
Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2021 April 03, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B).
The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.
The classified objects are listed in the Related Objects table below.
The redshift for SN2021gqm was obtained from the SNID template.
SN2021fmu has a rising light curve for 30 days, it has been suggested as a SLSN candidate (Lunnan et al. 2021TNSAN.102....1L), and previously classified as a SN (Prentice et al. 2021TNSCR.914....1P), but no discernible redshift. Redshift for this classification was taken from the Balmer lines.
