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…

A New Variable Modified Chaplygin Gas Model Interacting with Scalar Field

Writambhara Chakraborty, Ujjal Debnath

In this letter we present a new form of the well known Chaplygin gas model by introducing inhomogeneity in the EOS. This model explains crossing. Also we have given a graphi…

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…
