Description
Despite growing statistics, the sources of most high energy neutrinos remain unknown. Here we present a tomographic approach that makes use of the angular, harmonic cross-correlation between IceCube data and galaxy surveys. If neutrino sources follow the Large Scale Structure (LSS), this cross-correlation will be non-zero and, if detected, it will determine how neutrino sources correlate with the LSS via the linear bias and measure now the neutrino emissivity evolves with redshift, thereby allowing to exclude certain neutrino source models. In this proceedings we introduce our method and apply it to the 10-year IceCube data in combination with four galaxy catalogues covering redshifts up to z~3.
