A novel phenomenological parametrization of dynamical dark energy via matter-gravity coupling
Hrishikesh Chakrabarty, Daniele Malafarina
We develop a new parametrization for generic departures from the CDM model based on the Markov-Mukhanov action with non-minimal matter-gravity coupling. In this approach the cos…
Can UV meet IR in the Swiss cheese?
Madina Abilmazhinova, Diana Kulubayeva, Hrishikesh Chakrabarty +1
We consider the embedding of regular black holes in an expanding universe and study how the ultraviolet modifications to the Schwarzschild geometry that regularize the black hole s…
A unified model of dark energy and inflation from the Markov-Mukhanov action
Hrishikesh Chakrabarty, Daniele Malafarina
We propose a unified model of dark energy and inflation through the Markov-Mukhanov modification of the Einstein-Hilbert action, where the matter sector is coupled to gravity via a…
Observational properties of regular black holes in Asymptotic Safety
Abdybek Urmanov, Hrishikesh Chakrabarty, Daniele Malafarina
We consider the observational properties of a spherically symmetric, static regular black hole within the framework of asymptotic safety (AS) as proposed by Bonanno et al. The metr…
How to obtain slow roll inflation driven by non-linear electrodynamics
Daniele Malafarina, Hrishikesh Chakrabarty, Ilia Musco
We establish for the first time the conditions that must be imposed on the action for a magnetic universe in a theory of non-linear electrodynamics in order to have an asymptotical…
Running gravitational constant induced dark energy as a solution to tension
Tilek Zhumabek, Azamat Mukhamediya, Hrishikesh Chakrabarty +1
We consider a modified gravity model with a running gravitational constant coupled to a varying dark energy fluid and test its imprint on the growth of structure in the universe. U…
