چکیده انگلیسی
In the framework of coupled quintessence cosmologies, in which a quintessence scalar field mediates an interaction between matter fields, the case of growing neutrino models provides a nice explanation of the ‘why now’ problem. In these models the neutrino mass increases in time and stops the dynamical evolution of a dark energy scalar field when neutrinos become non relativistic. A new attractive force, mediated by quintessence, makes non relativistic neutrino form lumps on the scales of superclusters and beyond. Nonlinear neutrino lumps are predicted to form at redshift z≈1 and, if observed, could be an indication for a new attractive force stronger than gravity.
