Description
Superluminous supernovae (SLSNe) are rare transients that are $\sim 10 - 100$ times more luminous than ordinary stellar explosions, reaching peak optical luminosities $\sim 10^{44} - 10^{45}$ erg s$^{-1}$. The energy source powering SLSNe remains uncertain. In this talk, I will discuss the multi-wavelength and multi-messenger signatures from the scenario in which SLSNe are powered by a newly born millisecond magnetar. In particular, I will present the thermal and non-thermal electromagnetic and neutrino signatures. Interestingly for SN 2017egm, the nearest observed SLSNe, our prediction for high-energy gamma rays, matches the recent detection by Fermi LAT. I will show that, in the era of the Vera C. Rubin Observatory, a stacking analysis with upcoming neutrino observatories can lead to a $3\sigma$ detection significance of neutrino events from a population of SLSNe within a decade of operation.
