Exact solutions, finite time singularities and non-singular universe models from a variety of cosmologies
Supriya Pan
Cosmological models with time dependent (read as ) have been investigated widely in the literature. Models that solve background dynamics analytically, are of special int…
Cosmic chronometers constraints on some fast-varying dark energy equations of state
Rafael J. F. Marcondes, Supriya Pan
We consider three `four-parameters' dark energy equations of state allowing fast transition from the matter dominated decelerating phase to the current accelerating phase. The fast…
Novel approach towards the large-scale stable Interacting Dark-Energy models and their Astronomical Bounds
Weiqiang Yang, Supriya Pan, David F. Mota
Stability analysis of interacting dark energy models generally divides its parameters space into two regions: (i) and and (ii) and ,…
Perfect Fluid Cosmological Universes: One equation of state and the most general solution
Anadijiban Das, Asit Banerjee, Subenoy Chakraborty +1
Considering a homogeneous and isotropic universe characterized by the Friedmann-Lemaître-Robertson-Walker (FLRW) line element, in this work, we have prescribed a general formalism…
Constraining a dark matter and dark energy interaction scenario with a dynamical equation of state
Weiqiang Yang, Narayan Banerjee, Supriya Pan
In this work we have used the recent cosmic chronometers data along with the latest estimation of the local Hubble parameter value, at 2.4\% precision as well as the standard…
A new interacting two fluid model and its consequences
German S. Sharov, Subhra Bhattacharya, Supriya Pan +2
In the background of a homogeneous and isotropic spacetime with zero spatial curvature, we consider interacting scenarios between two barotropic fluids, one is the pressureless dar…
