ePESSTO+, the extended 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 Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C).

All observations were performed on the ESO New Technology Telescope at La Silla on 2019 April 25, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications are done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B), GELATO (Harutyunyan et al. 2008 2008A&A...488..383H) and Superfit (Howell et al. 2005 2005ApJ...634.1190H).

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 Notes correspond to the following:

(1) Redshift from host galaxy lines.
(2) Target chosen due to overlap with localisation map of S190425z.
