Perfect Fluid Cosmological Models with time-varying Constants
José Antonio Belinchón, Indrajit Chakrabarty
In this paper, we study in detail a perfect fluid cosmological model with time-varying "constants" using dimensional analysis and the symmetry method. We examine the case of variab…
Full Causal Bulk Viscous Cosmologies with time-varying Constants
José Antonio Belinchón, Indrajit Chakrabarty
We study the evolution of a flat Friedmann-Robertson-Walker Universe, filled with a bulk viscous cosmological fluid, in the presence of time varying ``constants''. The dimensional…
Quintessential Inflation with Dissipative fluid
A. A. Sen, Indrajit Chakrabarty, T. R. Seshadri
We have investigated cosmological models with a self-interacting scalar field and a dissipative matter fluid as the sources of matter. Different variables are expressed in terms of…
Gravitational Waves: An Introduction
Indrajit Chakrabarty
In this article, I present an elementary introduction to the theory of gravitational waves. This article is meant for students who have had an exposure to general relativity, but,…
