We use the high-resolution HR-DEMNUni simulations to compute cross-correlations of the Cosmic Neutrino Background C$_{\nu}$B with other observables, namely: cold dark matter density, effective weak lensing convergence, neutrino velocity and neutrino deflection angle.
We provide, for the first time, this high-fidelity cross-correlation maps in order to illustrate how much can be learned from them once the cosmic neutrino background is measured.
As cross-correlations will have more signal than auto-correlations of the C$_{\nu}$B itself, these might be the ones to be measured first by Ptolemy-like experiments.
Our predictions thus provide the imprint of what massive neutrinos should look like from cosmological observations.
