Super-SNID : an expanded set of SNID classes and templates for the new era of wide-field surveys

TL;DR

Super-SNID significantly expands the spectral template library for supernova identification, incorporating new classes and increasing spectra coverage, thereby enhancing classification capabilities for wide-field surveys.

Contribution

It introduces an expanded, easily integrable template library for SNID, including new supernova classes and more spectra, improving classification accuracy.

Findings

Includes 841 spectral templates for 161 objects.

Adds new supernova classes like SLSNe, TDEs, LFBOTs.

Enhances supernova classification for wide-field surveys.

Abstract

We present an expanded template library for the supernova identification (SNID) software, along with updated source files that make it easy to merge our templates - and other major SNID libraries - into the base code. This expansion, dubbed 'Super-SNID', increases the number of spectra for under-represented supernova classes (e.g., SNe Ia-02cx, Ibn) and adds new classes (e.g., SLSNe, TDEs, LFBOTs). Super-SNID includes 841 spectral templates for 161 objects, primarily from the Public ESO Spectroscopic Survey of Transient Objects (PESSTO) Data Releases 1-4. The library is available on GitHub with simple installation instructions.
