Nonlinear matter spectra in growing neutrino quintessence
N. Brouzakis, V. Pettorino, N. Tetradis +1
We investigate the nonlinear power spectra of density perturbations and acoustic oscillations in growing neutrino quintessence. In this scenario, the neutrino mass has a strong dep…

Effective cosmological equations of induced f(R) gravity
Pantelis S. Apostolopoulos, Nikolaos Brouzakis, Nikolaos Tetradis
We expand the study of generalized brane cosmologies by allowing for an gravity term on the brane, with the curvature scalar derived from the i…

Non-linear Matter Spectrum for a Variable Equation of State
N. Brouzakis, N. Tetradis
We study the growth of matter perturbations beyond the linear level in cosmologies in which the dark energy has a variable equation of state. The non-linear corrections result in s…
