Constraints on Neutrino Emission from Nearby Galaxies Using the 2MASS Redshift Survey and IceCube

Not scheduled


Mr Étienne Bourbeau (NBI)


The result of two searches for correlations between neutrinos and the matter in the Local Universe (z<0.03) is presented : A template analysis, which looks for neutrino emission patterns coming from collisions between ultra-high-energy cosmic rays (UHECR) and local galaxy matter, and a multiplet analysis, which looks for neutrino produced in low-luminosity sources within local galaxies. Both searches use the 2MASS Redshift Survey (2MRS) catalog as a proxy for the distribution of matter in the Local Universe, while the neutrino data taken from a seven-year sample developed for time-integrated searches of neutrino sources in the IceCube Neutrino Observatory.


Are the neutrinos observed by IceCube originating from galaxies in our local Universe? Probably Not!
