All-sky Search for High-Energy Neutrinos from Gravitational Wave Event GW170104 with the ANTARES Neutrino Telescope

TL;DR

This study conducted an all-sky search for high-energy neutrinos associated with the gravitational wave event GW170104 using the ANTARES telescope, but found no neutrino signals, thereby constraining the neutrino emission from the event.

Contribution

First all-sky high-energy neutrino follow-up for GW170104 with ANTARES, setting upper limits on neutrino emission from the black hole merger.

Findings

No neutrino candidates detected within ±500 s of GW170104

No clustering of neutrino events over ±3 months

Constraints placed on neutrino emission energy less than ~4×10^{54} erg

Abstract

Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4$^{\textrm{th}}$, 2017. An all-sky high-energy neutrino follow-up search has been made using data from the ANTARES neutrino telescope, including both upgoing and downgoing events in two separate analyses. No neutrino candidates were found within $\pm500$ s around the GW event time nor any time clustering of events over an extended time window of $\pm3$ months. The non-detection is used to constrain isotropic-equivalent high-energy neutrino emission from GW170104 to less than $\sim4\times 10^{54}$ erg for a $E^{-2}$ spectrum.
