Cosmic Bulk Flow Analysis in Modified Gravity Theories: $f (R)$ and Perturbed $f (R)$ Models with Neutrino Coupling

Muhammad Yarahmadi, Amin Salehi

In this study, we explore the characteristics of bulk flow across various redshift ranges within the frameworks of $f (R)$ gravity, perturbed $f (R)$ gravity, and perturbed $f (R)$ gr…

Using the Kaniadakis horizon entropy in the presence of neutrinos to alleviate the Hubble and $S_{8}$ Tensions

Muhammad Yarahmadi, Amin Salehi

The $H_{0}$ tension stands as a prominent challenge in cosmology, serving as a primary driver for exploring alternative models of dark energy. Another tension arises from measureme…
