Physical approximations for the nonlinear evolution of perturbations in dark energy scenarios
L. R. Abramo, R. C. Batista, L. Liberato +1
The abundance and distribution of collapsed objects such as galaxy clusters will become an important tool to investigate the nature of dark energy and dark matter. Number counts of…
Dynamical Mutation of Dark Energy
L. R. Abramo, R. C. Batista, L. Liberato +1
We discuss the intriguing possibility that dark energy may change its equation of state in situations where large dark energy fluctuations are present. We show indications of this…
Structure formation in the presence of dark energy perturbations
L. R. Abramo, R. C. Batista, L. Liberato +1
We study non-linear structure formation in the presence of dark energy. The influence of dark energy on the growth of large-scale cosmological structures is exerted both through it…
Dark energy parameterizations and their effect on dark halos
Lamartine Liberato, Rogerio Rosenfeld
There is a plethora of dark energy parameterizations that can fit current supernovae Ia data. However, this data is only sensitive to redshifts up to order one. In fact, many of th…
