Implications from ASKAP Fast Radio Burst Statistics

Understand

Although there has recently been tremendous progress in studies of fast radio bursts (FRBs), the nature of their progenitors remains a mystery.

• We study the fluence and dispersion measure (DM) distributions of the ASKAP sample to better understand their energetics and statistics.
• We first consider a simplified model of a power-law volumetric rate per unit isotropic energy dN/dE ~ E^{-gamma} with a maximum energy E_max in a uniform Euclidean Universe.
• This provides analytic insights for what can be learnt from these distributions.
