Blazars exhibit stochastic flux variability across the electromagnetic spectrum, often exhibiting heavy-tailed distributions, commonly modeled as lognormal. However, Tavecchio et al. (2020) and Adams (2022) found that high-energy gamma-ray distributions of several brightest flaring Fermi-LAT flat spectrum radio quasars (FSRQs) are well by an even heavier-tailed distribution, which we show is in...
