Neutrino clustering in growing neutrino quintessence
D. F. Mota, V. Pettorino, G. Robbers +1
A growing neutrino mass can stop the dynamical evolution of a dark energy scalar field, thus explaining the 'why now' problem. We show that such models lead to a substantial neutri…
Coupled and Extended Quintessence: theoretical differences and structure formation
Valeria Pettorino, Carlo Baccigalupi
The case of a coupling between dark energy and matter (Coupled Quintessence) or gravity (Extended Quintessence) has recently attracted a deep interest and has been widely investiga…
Scaling solutions in scalar-tensor cosmologies
Valeria Pettorino, Carlo Baccigalupi, Francesca Perrotta
The possibility of a connection between dark energy and gravity through a direct coupling in the Lagrangian of the underlying theory has acquired an increasing interest due to the…
Coupled quintessence and the coincidence problem
G. Mangano, G. Miele, V. Pettorino
We consider a model of interacting cosmological constant/quintessence, where dark matter and dark energy behave as, respectively, two coexisting phases of a fluid, a thermally exci…
