Abstract
We discuss the discovery potential of extended Very-High-Energy (VHE) neutrino sources by the future KM3 Neutrino Telescope (KM3NeT) in the context of the constraining power of the Cherenkov Telescope Array (CTA), designed for deep surveys of the sky in VHE gamma rays. The study is based on a comparative analysis of sensitivities of KM3NeT and CTA. We show that a minimum gamma-ray energy flux of E2Ïγ(10TeV)>1Ã10â12 TeV cmâ2 sâ1 is required to identify a possible neutrino counterpart with a 3Ï significance and 10 years of KM3NeT observations with upgoing muons, if the source has an angular size of Rsrc=0.1â and emits gamma rays with an Eâ2 energy spectrum through a full hadronic mechanism. This minimum gamma-ray flux is increased to the level of E2Ïγ(10TeV)>2Ã10â11 TeV cmâ2 sâ1 in case of sources with radial extension of Rsrc=2.0â. The analysis methods are applied to the supernova remnant RX J1713.7-3946 and the Galactic Center Ridge, as well as to the recent HAWC catalog of multi-TeV gamma-ray sources.
