Layzer-Irvine equation: new perspectives and the role of interacting dark energy
P. P. Avelino, A. Barreira
We derive the Layzer-Irvine equation in the presence of a homogeneous (or quasi-homogeneous) dark energy component with an arbitrary equation of state. We extend the Layzer-Irvine…

Chi-square versus median statistics in SNIa data analysis
A. Barreira, P. P. Avelino
In this paper we compare the performances of the chi-square and median likelihood analysis in the determination of cosmological constraints using type Ia supernovae data. We perfor…

Anthropic versus cosmological solutions to the coincidence problem
A. Barreira, P. P. Avelino
In this paper we investigate possible solutions to the coincidence problem in flat phantom dark energy models with a constant dark energy equation of state and quintessence models…
