Neutrino lumps and the Cosmic Microwave Background
Valeria Pettorino, Nico Wintergerst, Luca Amendola +1
The interaction between the cosmon and neutrinos may solve the "why now problem" for dark energy cosmologies. Within growing neutrino quintessence it leads to the formation of nonl…
Clarifying spherical collapse in coupled dark energy cosmologies
Nico Wintergerst, Valeria Pettorino
The spherical collapse model is often used to follow the evolution of overdensities into the nonlinear regime. We describe the correct approach to be used in coupled dark energy co…
Very large scale structures in growing neutrino quintessence
Nico Wintergerst, Valeria Pettorino, David F. Mota +1
A quintessence scalar field or cosmon interacting with neutrinos can have important effects on cosmological structure formation. Within growing neutrino models the coupling becomes…
