# Superluminous supernovae at high redshift

## TL;DR

This paper reviews the discovery and potential mechanisms of superluminous supernovae observed at high redshifts, including during the epoch of reionization.

## Contribution

It provides a comprehensive overview of candidate mechanisms and discovery programs for high-redshift superluminous supernovae.

## Key findings

- Superluminous supernovae are observed at redshifts during reionization.
- Multiple mechanisms are proposed to explain their luminosity.
- Discovery programs are actively identifying these distant supernovae.

## Abstract

Superluminous supernovae are beginning to be discovered at redshifts as early as the epoch of reionization. A number of candidate mechanisms is reviewed, together with the discovery programs.
