Contraining Astrophysical Neutrino Sources through Large Scale Structure

Despite growing statistics, the sources of high energy neutrinos remain unknown. Direct source association and stacking analysis have only been able to account for a small fraction of the astrophysical neutrino flux. Here we present an approach that builds on previous work to this problem 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 should be non zero. If detected, we could learn about how neutrino sources correlate with the LSS via the linear bias and calculate the neutrino emissivity. In this proceedings we show the method to do this while focusing on constraining physical parameters. In the future this information could be used to exclude certain neutrino source models.
