Dynamical system analysis of interacting dark energy-matter scenarios at the linearized inhomogeneous level
Mohit Kumar Sharma, Sourav Sur
We carry out the dynamical system analysis of interacting dark energy-matter scenarios by examining the critical points and stability for not just the background level cosmological…
Imprints of interacting dark energy on cosmological perturbations
Mohit Kumar Sharma, Sourav Sur
We investigate the characteristic modifications in the evolving cosmological perturbations when dark energy interacts with dust-like matter, causing the latter's background energy…
Observational constraints on the massive neutrinos induced late-time cosmic acceleration
Mohit K. Sharma, Shibesh Kumar Jas Pacif, Shynaray Myrzakul +1
We study a scenario based upon a mass-less theory coupled to massive neutrino matter with symmetry using a conformal coupling, …
Late time acceleration due to generic modification of gravity and Hubble tension
Shahnawaz A. Adil, Mayukh R. Gangopadhyay, M. Sami +1
We consider a scenario of modified gravity, which is generic to late-time acceleration, namely, acceleration in the Jordan frame and no acceleration in the Einstein frame. The poss…
On the quantum origin of a dark universe
Saurya Das, Mohit Kumar Sharma, Sourav Sur
It has been shown beyond reasonable doubt that the majority (about 95%) of the total energy budget of the universe is given by the dark components, namely Dark Matter and Dark Ener…
Growth of matter perturbations in an interacting dark energy scenario emerging from metric-scalar-torsion couplings
Mohit Kumar Sharma, Sourav Sur
We study the growth of linear matter density perturbations in a modified gravity approach of scalar field couplings with metric and torsion. In the equivalent scalar-tensor formula…
