Accelerating Expansion of the Universe
Writambhara Chakraborty
This thesis concentrates on the accelerated expansion of the Universe recently explored by measurements of redshift and luminosity-distance relations of type Ia Supernovae. We have…
Role of Brans-Dicke Theory with or without self-interacting potential in cosmic acceleration
Writambhara Chakraborty, Ujjal Debnath
In this work we have studied the possibility of obtaining cosmic acceleration in Brans-Dicke theory with varying or constant (Brans- Dicke parameter) and with or without self-i…
Role of Tachyonic Field in Accelerating Universe in Presence of Perfect Fluid
Writambhara Chakraborty, Ujjal Debnath
Recently tachyonic field has been depicted as dark energy model to represent the present acceleration of the Universe. In this paper we have considered mixture of tachyonic fluid w…
Interaction between scalar field and ideal fluid with inhomogeneous equation of state
Writambhara Chakraborty, Ujjal Debnath
In this letter we study a model of interaction between the scalar field and an inhomogeneous ideal fluid. We have considered two forms of the ideal fluid and a power law expansion…
Generalized Cosmic Chaplygin Gas Model with or without Interaction
Writambhara Chakraborty, Ujjal Debnath, Subenoy Chakraborty
Recently developed Generalized Cosmic Chaplygin gas (GCCG) is studied as an unified model of dark matter and dark energy. To explain the recent accelerating phase, the Universe is…
Is Modified Chaplygin gas along with barotropic fluid responsible for acceleration of the Universe?
Writambhara Chakraborty, Ujjal Debnath
In this letter, we have considered a model of the universe filled with modified Chaplygin gas and another fluid (with barotropic equation of state) and its role in accelerating pha…
