This study investigates the cosmological implications of gravity by reconstructing the Hubble parameter from a logarithmic parameterization of the diagnostic.…
Effective CDM model emerging from under a special EOS limit in symmetric cosmology with Bayesian and ANN observational constraints
Anil Kumar Yadav, S. H. Shekh, N. Myrzakulov +3
In this work, we investigate the cosmological consequences of an effective CDM model emerging from the more general gravity theory under the special equation-of-state c…
Observational constraints using Bayesian statistics and Deep Learning in gravity
Lokesh Kumar Sharma, Suresh Parekh, Anil Kumar Yadav
This study investigates the evolution of Friedmann-Robertson-Walker (FRW) cosmological models within the gravity framework, utilizing a specific formulation and a nov…
Cosmological Evolution of Viscous Dark Energy in f(Q,C) Gravity: Two-Fluid Approach
N. Myrzakulov, Anirudh Pradhan, S. H. Shekh
In this paper, we study the cosmological evolution of a viscous dark energy model within the framework of gravity, utilizing a two-fluid approach. The model incorporates…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
