Unveiling the Effects of Coupling Extended Proca-Nuevo Gravity on Cosmic Expansion with Recent Observations
L. Sudharani, N. S. Kavya, V. Venkatesha
We study Coupling Extended Proca-Nuevo gravity, a non-linear theory extending from dRGT massive gravity with a spin-1 field. This theory is shown to yield reliable, ghost-free cosm…

Governing accelerating Universe via newly reconstructed Hubble parameter by employing empirical data simulations
L. Sudharani, Kazuharu Bamba, N. S. Kavya +1
A new parametrization of the Hubble parameter is proposed to explore the issue of the cosmological landscape. The constraints on model parameters are derived through the Markov Cha…
