title = "VERITAS and Fermi-LAT Constraints on the Gamma-Ray Emission from Superluminous Supernovae SN2015bn and SN2017egm",
abstract = "Superluminous supernovae (SLSNe) are a rare class of stellar explosions with luminosities ~ 10-100 times greater than ordinary core-collapse supernovae. One popular model to explain the enhanced optical output of hydrogenpoor (Type I) SLSNe invokes energy injection from a rapidly spinning magnetar. A prediction in this case is that high-energy gamma-rays, generated in the wind nebula of the magnetar, could escape through the expanding supernova ejecta at late times (months or more after optical peak). This paper presents a search for gamma-ray emission in the broad energy band from 100 MeV to 30 TeV from two Type I SLSNe, SN2015bn, and SN2017egm, using observations from Fermi-LAT and VERITAS. Although no gamma-ray emission was detected from either source, the derived upper limits approach the putative magnetar's spin-down luminosity. Prospects are explored for detecting very-high-energy (VHE; 100 GeV-100 TeV) emission from SLSNe-I with existing and planned facilities such as VERITAS and CTA.",
