Large-scale (in-) stability Analysis of an Exactly Solved Coupled Dark-Energy Model

Weiqiang Yang, Supriya Pan, Ramón Herrera +1

Assuming a non-gravitational interaction amongst the dark fluids of our universe namely, the dark matter and dark energy, we study a specific interaction model in the background of…

Tale of stable interacting dark energy, observational signatures, and the tension

Weiqiang Yang, Supriya Pan, Eleonora Di Valentino +3

We investigate the observational consequences of a novel class of stable interacting dark energy (IDE) models, featuring interactions between dark matter (DM) and dark energy (DE).…

Cosmological constraints on an exponential interaction in the dark sector

Weiqiang Yang, Supriya Pan, Andronikos Paliathanasis

Cosmological models where dark matter (DM) and dark energy (DE) interact with each other are the general scenarios in compared to the non-interacting models. The interaction is usu…

Effects of Anisotropic Stress in Interacting Dark Matter - Dark Energy Scenarios

Weiqiang Yang, Supriya Pan, Lixin Xu +1

We study a novel interacting dark energy dark matter scenario where the anisotropic stress of the large scale inhomogeneities is considered. The dark energy has a constant equa…

Limiting curvature mimetic gravity and its relation to Loop Quantum Cosmology

Jaume de Haro, Llibert Aresté Saló, Supriya Pan

Considering as usual that the underlying geometry of our universe is well described by the spatially flat Friedmann-Lemaitre-Robertson-Walker line element, we review how the backgr…

Cosmological Time Crystal: Cyclic Universe with a small in a toy model approach

Praloy Das, Supriya Pan, Subir Ghosh +1

A new form Time Crystal has been proposed and some of its consequences have been studied. The model is a generalization of the Friedmann-Robertson-Walker (FRW) cosmology endowed wi…

Observational Constraints on Oscillating Dark-Energy Parametrizations

Supriya Pan, Emmanuel N. Saridakis, Weiqiang Yang

We perform a detailed confrontation of various oscillating dark-energy parame-trizations with the latest sets of observational data. In particular, we use data from Joint Light Cur…

Latest astronomical constraints on some nonlinear parametric dark energy models

Weiqiang Yang, Supriya Pan, Andronikos Paliathanasis

We consider nonlinear redshift-dependent equation of state parameters as dark energy models in a spatially flat Friedmann-Lemaître-Robertson-Walker universe. To depict the expansio…

Large-scale Stability and Astronomical Constraints for Coupled Dark-Energy Models

Weiqiang Yang, Supriya Pan, John D. Barrow

We study large-scale inhomogeneous perturbations and instabilities of interacting dark energy (IDE) models. Past analysis of large-scale perturbative instabilities, has shown that…
