Title: Multiwavelength Signals From Pulsar-Driven Supernovae

Abstract:
The pulsar-driven supernova model, where the initial radiation is powered by the nebula of a rapidly rotating, highly magnetized neutron star, is commonly used to explain superluminous supernovae (SLSNe) and some gamma-ray bursts (GRBs), but has yet to be confirmed. Quasi-thermal optical supernova emission can not differentiate between different engines (ie. pulsar wind nebulae (PWNe) or fallback onto a black hole), but there may be late-phase non-thermal emission unique to a pulsar engine. I'll overview our theoretical predictions for direct detection of PWN emission in the radio band and indirect detection via dust re-radiation in the infrared, as well as our radio observations that have tested and constrained the model.
