Time and distance constraints on accelerating cosmological models
M. A. Dantas, J. S. Alcaniz, D. Mania +1
The absence of guidance from fundamental physics about the mechanism behind cosmic acceleration has given rise to a number of alternative cosmological scenarios. These are based ei…

Observational tests for Λ(t)CDM cosmology
C. Pigozzo, M. A. Dantas, S. Carneiro +1
We investigate the observational viability of a class of cosmological models in which the vacuum energy density decays linearly with the Hubble parameter, resulting in a production…

Using a phenomenological model to test the coincidence problem of dark energy
Yun Chen, Zong-Hong Zhu, J. S. Alcaniz +1
By assuming a phenomenological form for the ratio of the DE and DM densities (Dalal et al.2001), we discuss the cosmic coincidence problem in light of curren…
