Compact stellar models in modified gravity
Ines G. Salako, Chayan Ranjit, M. Khlopov +2
In the present investigation compact stellar models are dealt with in the framework of the modified gravity theory, specifically of type. We have consid…
Generalized Model for -Dark Energy
Utpal Mukhopadhyay, P. C. Ray, Saibal Ray +1
Einstein field equations under spherically symmetric space-times are considered here in connection to dark energy investigation. A set of solutions are obtained for a kinematical $…
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 by selecting a phenomenological model of the form, . This si…
Scenario of inflationary cosmology from the phenomenological models
Saibal Ray, P. C. Ray, Partha Pratim Ghosh +2
Choosing the three phenomenological models of the dynamical cosmological term , viz., , and where is the cosmic scale facto…
-CDM Universe: A Phenomenological Approach With Many Possibilities
U. Mukhopadhyay, Saibal Ray, S. B. Dutta Choudhury
A time-dependent phenomenological model of , viz. is selected to investigate the -CDM cosmology. Time-dependent form of the equation of state parameter i…
