In a previous work, we report evidence for a spatial correlation between blazars from the 5th Roma-BZCat catalog and neutrino data of the highest detectable energies, i.e. >0.1 PeV, collected by the IceCube Observatory in the southern celestial hemisphere. The statistical significance is found at the level of 2 x 10^{-6} post-trial. In this work we test whether a similar correlation exists in the northern hemisphere, were IceCube is mostly sensitive to <0.1 PeV energies.
