The Energy Function and Cosmic Formation Rate of Fast Radio Bursts

Understand

Fast radio bursts (FRBs) are intense radio transients whose physical origin remains unknown.

• Therefore, it is of crucial importance to use a model-independent method to obtain the energy function and cosmic formation rate directly from the observational data.
• Based on current samples from the Parkes and ASKAP telecsopes, we determine, for the first time, the energy function and formation rate of FRBs by using the Lynden-Bell $\rm C^{-}$ method.
• The energy function derived from the Parkes sample is a broken power law, however it is a simple power law for the ASKAP sample.
