The Limit of the Generalized Chaplygin Gas Scenario
P. P. Avelino, L. M. G. Beca, J. P. M. de Carvalho +1
We explicitly demonstrate that, contrary to recent claims, the dynamics of a generalized Chaplygin gas model with an equation of state (where is a positive constant) is…
The onset of the non-linear regime in unified dark matter models
P. P. Avelino, L. M. G. Beca, J. P. M. de Carvalho +2
We discuss the onset of the non-linear regime in the context of unified dark matter models involving a generalised Chaplygin gas. We show that the transition from dark matter-like…
The Role of Baryons in Unified Dark Matter Models
L. M. G. Beca, P. P. Avelino, J. P. M. de Carvalho +1
We discuss the importance of including baryons in analyses of unified dark matter scenarios, focusing on toy models involving a generalized Chaplygin gas. We determine observationa…
