Superluminous supernovae (SLSNe) are a population of supernovae (SNe) whose peak luminosities are much larger than those of canonical SNe. Although SLSNe were simply defined by their peak luminosity at first, it is currently recognized that they show rich spectroscopic diversities including hydrogen-poor (Type I) and hydrogen-rich (Type II) subtypes. The exact mechanisms making SLSNe luminous are still not fully understood, but there are mainly four major suggested luminosity sources (radioactive decay of 56Ni, circumstellar interaction, magnetar spin-down, and fallback accretion). We provide an overview of observational properties of SLSNe and major theoretical models for them. Future transient surveys are expected to discover SLSNe at high redshifts which will provide a critical information in revealing their nature.

  1. AT2019ijn: a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission

    astro-ph.HE 2026-07 conditional novelty 7.0

    AT2019ijn combines LFBOT-like fast optical rise and blue color with slow decay and radio luminosity peaking late at 2e31 erg/s/Hz, best fit as an off-axis jetted IMBH TDE.

  2. Bridging the gap between SLSNe and SE-SNe. Multi-wavelength analysis of the SLSN-Ib SN 2024jlc

    astro-ph.HE 2026-07 unverdicted novelty 4.0

    Multi-wavelength analysis of SN 2024jlc classifies it as an SLSN-Ib whose light curve fits circumstellar interaction or magnetar spin-down plus nickel decay, suggesting it bridges to SE-SNe via powering mechanism.

  3. Supernovae with the Square Kilometre Array

    astro-ph.HE 2026-06 unverdicted novelty 3.0

    This review chapter updates prior work to outline the SKA's expected role in turning radio observations of supernovae into population statistics through wide-field surveys and targeted follow-up.
