Abstract

he blazar TXS 0506+056 underwent a major gamma-ray flare in 2017, lasting more than a year.The continuous gamma-ray data available during the flare and the long duration of the flare areadvantageous to study the neutrino emission potential of the source, assuming correlation betweenthe observed gamma flux and the neutrino flux. KM3NeT-ARCA is an upcomingkm3CherenkovTelescope in the Mediterranean Sea, capable of studying astrophysical point-sources of neutrinoswith a median angular resolution of upto 0.1◦.In this contribution, the sensitivity and discovery potential of the KM3NeT-ARCA detector toTXS 0506+056 are reported as a function of time during its flare. For a gamma-ray flare with thesame luminosity as that of 2017-18, we find that KM3NeT-ARCA would need six months or lessto detect the source, depending on the model assumed. Assuming a constant average flux, thesource would be detectable with a significance > 5σ in 2 years of observation.
