The dark energy equation of state

A. A. Usmani, P. P. Ghosh, Utpal Mukhopadhyay +2

We perform a study of cosmic evolution with an equation of state parameter $ω (t) = ω_{0} + ω_{1} (t H ˙ / H)$ by selecting a phenomenological $Λ$ model of the form, $Λ ˙ \sim H^{3}$ . This si…

Scenario of inflationary cosmology from the phenomenological $Λ$ models

Saibal Ray, P. C. Ray, Partha Pratim Ghosh +2

Choosing the three phenomenological models of the dynamical cosmological term $Λ$ , viz., $Λ \sim (a ˙ / a)^{2}$ , $Λ \sim a ¨ / a$ and $Λ \sim ρ$ where $a$ is the cosmic scale facto…

Large Number Hypothesis: A Review

Saibal Ray, Utpal Mukhopadhyay, Partha Pratim Ghosh

Large dimensionless numbers, arising out of ratios of various physical constants, intrigued many scientists, especially Dirac. Relying on the coincidence of large numbers, Dirac ar…
