A Search for Coincident Neutrino Emission from Fast Radio Bursts with Seven Years of IceCube Cascade Events

Abstract

This paper presents the results of a search for neutrinos that are spatially and temporally coincident with 22 unique, nonrepeating fast radio bursts (FRBs) and one repeating FRB (FRB 121102). FRBs are a rapidly growing class of Galactic and extragalactic astrophysical objects that are considered a potential source of high-energy neutrinos. The IceCube Neutrino Observatory’s previous FRB analyses have solely used track events. This search utilizes seven years of IceCube cascade events which are statistically independent of track events. This event selection allows probing of a longer range of extended timescales due to the low background rate. No statistically significant clustering of neutrinos was observed. Upper limits are set on the time-integrated neutrino flux emitted by FRBs for a range of extended time windows.

High-energy Neutrinos from Gamma-Ray-faint Accretion-powered Hypernebulae

“…A population of FRBs could be powered by flares along hyper-Eddington accretion disk jets (Sridhar et al 2021a;Bhandari et al 2023). Recently, Abbasi et al (2023a) presented the search results for spatially and temporally coincident neutrino emission from FRBs with IceCube Cascade data, and found no significant clustering around the short-lived and beamed FRB event. This result is in agreement with theoretical predictions (Metzger et al 2020).…”

A stacked search for spatial coincidences between IceCube neutrinos and radio pulsars

“…A number of extragalactic sources have been considered which could contribute to the diffuse neutrino flux, such as blazars and other types of AGNs, star-forming galaxies, FRBs, GRBs, galaxy clusters, other ancillary extragalactic sources in Fermi-LAT catalog, etc by both the IceCube collaboration, and others using the publicly available IceCube dataset. A non-exhaustive list includes searches for correlation with extra-galactic sources such as AGNs and GRBs [4][5][6][7][8][9][10][11][12], FRBs [13][14][15], high energetic events from the Fermi-LAT catalog [8,16], and galaxy catalogs using the 2MASS survey [17].…”
