Fast radio bursts trigger aftershocks resembling earthquakes, but not solar flares
Tomonori Totani, Yuya Tsuzuki

TL;DR
Repeating fast radio bursts exhibit earthquake-like aftershock patterns in their timing and energy correlations, suggesting a seismic origin related to neutron star crust activity, distinct from solar flare behaviors.
Contribution
This study introduces a correlation function analysis revealing earthquake-like aftershock patterns in FRBs, a novel approach linking FRB activity to neutron star seismic processes.
Findings
FRBs show power-law aftershock decay similar to earthquakes
No correlation between burst energy and waiting time
Distinct from solar flare activity in correlation patterns
Abstract
The production mechanism of repeating fast radio bursts (FRBs) is still a mystery, and correlations between burst occurrence times and energies may provide important clues to elucidate it. While time correlation studies of FRBs have been mainly performed using wait time distributions, here we report the results of a correlation function analysis of repeating FRBs in the two-dimensional space of time and energy. We analyze nearly 7,000 bursts reported in the literature for the three most active sources of FRB 20121102A, 20201124A, and 20220912A, and find the following characteristics that are universal in the three sources. A clear power-law signal of the correlation function is seen, extending to the typical burst duration ( 10 msec) toward shorter time intervals (. The correlation function indicates that every single burst has about a 10-60% chance of producing an…
