The nonlinear evolution of large scale structures in Growing Neutrino cosmologies

We present the results of the first N-body simulations of the Growing Neutrino scenario, as recently discussed in Baldi et al. (2011). Our results have shown for the first time how neutrino lumps forming in the context of Growing Neutrino cosmologies are expected to pulsate as a consequence of the rapid oscillations of the dark energy scalar field. We have also computed for the first time a realistic statistical distribution of neutrino halos and determined their impact on the underlying Cold Dark Matter structures.
