The Amplitude-Growth Degeneracy and Implied Diagnostic for Background-Inert Modified Gravity
Ameya Kolhatkar, P. K. Sahoo
We prove that any background-inert perturbative coupling in coincident gravity exhibits a degeneracy with the clustering amplitude , when using compressed C…
Beyond the Cosmological Constant: Breaking the Geometric Degeneracy of cosmology via Redshift-Space Distortions
Ameya Kolhatkar, P. K. Sahoo
We present a rigorous theoretical and observational analysis of the Hybrid class of models by including the late-time modifying term. After deriving strict viabili…
Investigating early and late-time epochs in gravity
Ameya Kolhatkar, Sai Swagat Mishra, P. K. Sahoo
In the following work, a new hybrid model of the form has been proposed and confronted using both early as well as late-time constraints. We first…
Big Bang Nucleosynthesis constraints on gravity
Sai Swagat Mishra, Ameya Kolhatkar, P. K. Sahoo
Big Bang Nucleosynthesis provides us with an observational insight into the very early Universe. Since this mechanism of light element synthesis comes out of the standard model of…
Correction to Lagrangian for Bouncing Cosmologies in Gravity
Gaurav N. Gadbail, Ameya Kolhatkar, Sanjay Mandal +1
Symmetric teleparallel gravity offers to reformulate the gravitational formalism without the presence of curvature and torsion with the help of non-metricity tensors. Interestingly…
Gravitational Collapse of Massless Vector Field with Positive Cosmological Constant
Tapobroto Bhanja, Ameya Kolhatkar
We investigate the dynamics of homogeneous gravitational collapse of a massless vector field in the presence of a positive cosmological constant . The corresponding density func…
