A Significant Association Between CHIME Fast Radio Bursts and Low-Energy IceCube Neutrinos [HEAP]

http://arxiv.org/abs/2112.11375


Despite numerous studies, the sources of IceCube cosmic neutrinos have hitherto been unidentified. Utilizing recently released IceCube neutrino and CHIME FRB catalogs, we examine the possibility of an association between neutrinos and FRBs for both the entire FRB population and individual FRBs using the directional matching method. We report an association between FRBs and low-energy IceCube neutrinos with energies 0.1 — 3 TeV at a significance level of $21.3 \sigma$. We also identify 20 FRBs that are candidate association sources of neutrinos, all of which are apparently non-repeating FRBs. This sub-sample of FRBs shows no special properties compared with the whole CHIME FRB sample. We discuss the possible physical origin of such associations within the framework of the magnetar models of FRBs.
