A search for neutrinos from fast radio bursts with IceCube

TL;DR

This study searched for neutrinos coincident with four fast radio bursts using IceCube data, but found no associated neutrinos, setting upper limits on neutrino fluence from FRBs.

Contribution

First search for neutrinos from FRBs with IceCube, providing upper limits on neutrino emission associated with these transient events.

Findings

No neutrinos detected in coincidence with FRBs.

Established the first upper limits on neutrino fluence from FRBs.

Demonstrated IceCube's capability to constrain neutrino emission from transient sources.

Abstract

We present a search for neutrinos in coincidence in time and direction with four fast radio bursts (FRBs) detected by the Parkes and Green Bank radio telescopes during the first year of operation of the complete IceCube Neutrino Observatory (May 2011 through May 2012). The neutrino sample consists of 138,322 muon neutrino candidate events, which are dominated by atmospheric neutrinos and muons but also contain an astrophysical neutrino component. Considering only neutrinos detected on the same day as each FRB, zero IceCube events were found to be compatible with the FRB directions within the estimated 99\% error radius of the neutrino directions. Based on the non-detection, we present the first upper limits on the neutrino fluence from fast radio bursts.
