Advanced LIGO detected a significant gravitational wave signal (GW170104)
originating from the coalescence of two black holes during the second
observation run on January 4th, 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 ±500 s around the GW
event time nor any time clustering of events over an extended time window of
±3 months. The non-detection is used to constrain isotropic-equivalent
high-energy neutrino emission from GW170104 to less than ∼4×1054
erg for a E−2 spectrum
