The IceCube Neutrino Observatory has measured a diffuse all-sky all-flavor astrophysical neutrino flux above 30TeV. Nevertheless, dedicated searches for astrophysical neutrino point sources have not yet been successful, and the question about the production sites of astrophysical neutrinos remains inconclusive. There are, however, several theoretical models predicting classes of extragalactic sources which are abundant, but too faint to be detected individually. These weak sources could leave an overall signature in an angular-correlation analysis.
This talk presents the latest results from an angular correlation analysis performed on 6 years of IceCube data using the multipole expansion coefficients of spherical harmonics. The resulting implications for particularly interesting source classes such as Blazars and Fanaroff-Riley or Starburst Galaxies are discussed.
