Some New Types of Well-Behaved Polynomial Redshift Parametrization of Dark Energy Equation of State
Prabir Rudra, Aritra Sanyal, Promila Biswas +3
In this paper, we explore a new type of smooth and well-behaved polynomial redshift function that can avoid a future singularity. Using this function, we have proposed different re…
Godel Universe in gravity: Exploring causality violation and closed time-like curves
Tuhina Ghorui, Prabir Rudra, Farook Rahaman
In this work, the classical Godel solution from general relativity is extended into the framework of modified gravity theories based on non-metricity and the trace of the energ…
Warm Inflation in gravity
Tuhina Ghorui, Prabir Rudra, Farook Rahaman +1
We investigate warm inflation in the framework of gravity within a Friedmann-Robertson-Walker spacetime. Unlike cold inflation, where the inflaton evolves in isolation, warm…
A new type of gravity from Barrow entropy
Tuhina Ghorui, Prabir Rudra, Farook Rahaman
In this work, two originally separate adjustments for the Friedmann equations are concurrently considered. Firstly, the fractal structure of the black hole horizon region is impose…
