The IceCube Neutrino Observatory is a cubic kilometer neutrino telescope located in the Antarc-
tic ice. Recently, IceCube has measured a diffuse all-sky all-flavor astrophysical neutrino flux
above 30 TeV. However, the origin and production of these particles still remain unknown. Given
the observed flux, the absence of observations of bright point-sources could be explained by a
large population of weak sources. This scenario can be tested using autocorrelation methods. We
present here the results of two independent analyses on two different neutrino samples based on
6 and 7 years of IceCube data. The first sample is optimized for events coming from the Northern
Hemisphere, while the second one is an all-sky sample. Experimental results are obtained by an-
alyzing these samples using a multipole expansion and a two-point angular correlation technique,
respectively. In addition, flux upper limits for extended sources and the Cygnus region have been
