Intensity Distribution Function and Statistical Properties of Fast Radio Bursts

Understand

Fast Radio Bursts (FRBs) are intense radio flashes from the sky that are characterized by millisecond durations and Jansky-level flux densities.

• We carried out a statistical analysis on FRBs discovered.
• Their mean dispersion measure, after subtracting the contribution from the interstellar medium of our Galaxy, is found to be $\sim 660\,\rm pc\,cm^{-3}$, supporting their being from cosmological origin.
• Their energy released in radio band spans about two orders of magnitude, with a mean value of $\sim 10^{39}$ ergs.
