A Search for Late-Time Radio Emission and Fast Radio Bursts from Superluminous Supernovae

Understand

We present results of a search for late-time radio emission and Fast Radio Bursts (FRBs) from a sample of type-I superluminous supernovae (SLSNe-I).

• We used the Karl G.
• Jansky Very Large Array to observe ten SLSN-I more than 5 years old at a frequency of 3 GHz.
• We searched fast-sampled visibilities for FRBs and used the same data to perform a deep imaging search for late-time radio emission expected in models of magnetar-powered supernovae.
