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…
Constraints on dark energy from the lookback time versus redshift test
Lado Samushia, Abha Dev, Deepak Jain +1
We use lookback time versus redshift data from galaxy clusters (Capozziello et al., 2004) and passively evolving galaxies (Simon et al., 2005), and apply a bayesian prior on the to…
Delicate f(R) gravity models with disappearing cosmological constant and observational constraints on the model parameters
Abha Dev, D. Jain, S. Jhingan +3
We study the theory of gravity using metric approach. In particular we investigate the recently proposed model by Hu-Sawicki, Appleby Battye and Starobinsky. In this mod…
Power law cosmology - a viable alternative
Abha Dev, Deepak Jain, Daksh Lohiya
A power law cosmology is defined by the cosmological scale factor evolving as . In this work, we put bounds on by using the joint test of the SNe Ia data from Supernova Le…
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…
Age constraints on the cosmic equation of state
M. A. Dantas, J. S. Alcaniz, Deepak Jain +1
Dark energy is the invisible fuel that seems to drive the current acceleration of the Universe. Its presence, which is inferred from an impressive convergence of high-quality obser…
