Constraining dark matter-dark energy interaction with gas mass fraction in galaxy clusters
R. S. Goncalves, J. S. Alcaniz, A. Dev +1
The recent observational evidence for the current cosmic acceleration have stimulated renewed interest in alternative cosmologies, such as scenarios with interaction in the dark se…
A generalized equation of state for dark energy
E. M. Barboza, J. S. Alcaniz, Zong-Hong Zhu +1
A generalized parameterization for the dark energy equation of state (EoS) is proposed and some of its cosmological consequences are investigated. We show that in the limi…
Non-gaussian statistics and the relativistic nuclear equation of state
F. I. M. Pereira, R. Silva, J. S. Alcaniz
We investigate possible effects of quantum power-law statistical mechanics on the relativistic nuclear equation of state in the context of the Walecka quantum hadrodynamics theory.…
Current lookback time-redshift bounds on dark energy
M. A. Dantas, J. S. Alcaniz, N. Pires
We investigate observational constraints on dark energy models from lookback time (LT) estimates of 32 old passive galaxies distributed over the redshift interval $0.11 \leq z \leq…
A parametric model for dark energy
E. M. Barboza, J. S. Alcaniz
Determining the mechanism behind the current cosmic acceleration constitutes a major question nowadays in theoretical physics. If the dark energy route is taken, this problem may p…
Cosmological bounds on oscillating dark energy models
Deepak Jain, Abha Dev, J. S. Alcaniz
We study some cosmological constraints on the two phenomenological models of oscillating dark energy. In these scenarios, the equation of state of dark energy varies periodically a…
