High-energy emitting BL Lacs and high-energy neutrinos Prospects for the direct association with IceCube and KM3NeT.

Abstract (from CDS):

Context. The origin of the high-energy flux of neutrinos detected by IceCube remains unknown. Recent works report evidence for a possible positional correlation between the reconstructed neutrino arrival directions and the positions in the sky of low-power, high-energy-emitting BL Lac objects (HBL).
Aims. Assuming that γ-ray-emitting HBL form the bulk of the sources of high-energy neutrinos above 100TeV, we intend to calculate the number of events expected to be detected for each source by IceCube and KM3NeT.
Methods. Based on a simple theoretically-motivated framework inspired by the structured jet scenario for these sources, we postulate a direct proportionality between high-energy γ-ray and neutrino fluxes. We calculate the expected neutrino event rate for the HBL sources of the Second Fermi-LAT Catalog of High-Energy Sources (2FHL) for IceCube and the presently under-construction KM3NeT using declination-dependent and exposure-weighted effective areas.
Results. We provide a list of 2FHL HBL with the calculated number of events. For IceCube, the derived count rate for several sources is relatively high, of the order of ≤1yr–1, consistent with the recent findings of a possible positional correlation. For KM3NeT, the calculated rates are higher, with several sources with expected rates exceeding 1yr–1. This, coupled with the improved angular resolution, implies that the HBL origin can be effectively tested with few years of observation of KM3NeT (and IceCube Gen2, for which similar performances are foreseen) through the direct association of neutrinos and single HBL.
Conclusions. Our results show that if, as suggested by recent works, HBL represent a possible population of high-energy neutrino emitters, several single sources should be identified in a few years of exposure of KM3NeT, highlighting the importance of the improved angular resolution anticipated for KM3NeT and IceCube Gen2.
