Abstract
We show that growing neutrino models, in which the growing neutrino mass stops the dynamical evolution of a dark energy scalar field, lead to a substantial neutrino clustering on the scales of superclusters. Nonlinear neutrino lumps form at redshift z ~ 1 and could partially drag the clustering of dark matter. If observed, large scale non-linear structures could be an indication for a new attractive force stronger than gravity and mediated by the 'cosmon' dark energy scalar field.
