Evolution of scalar and vector cosmological perturbations through a bounce in metric gravity in flat FLRW spacetime
Pritha Bari, Kaushik Bhattacharya
In the present work we present the full treatment of scalar and vector cosmological perturbations in a non-singular bouncing universe in the context of metric cosmology. Sca…
Early universe cosmological solutions in exponential gravity
Pritha Bari, Kaushik Bhattacharya, Saikat Chakraborty
In this work we present some cosmologically relevant solutions using the spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime in metric gravity where the form…
Causal horizons in a bouncing universe
Kaushik Bhattacharya, Pritha Bari, Saikat Chakraborty
As our understanding of the past in a bouncing universe is limited, it becomes difficult to propose a cosmological model which can give some understanding of the causal structure o…
