Entropic Chaplygin-Gas cosmology and late-universe tension diagnostics

Kelvis A. Kulhkampa, Carlos H. Coimbra-Araújob, Abraão J. S. Capistrano +2

We investigate an entropic generalized Chaplygin-gas (gCg) cosmology in which a single dark fluid accounts for both dark matter and dark energy. We constrain the model using DESI b…

Linear Nash-Greene fluctuations on the evolution of $S_{8}$ and $H_{0}$ tensions

Abraão J. S. Capistrano, Luís A. Cabral, José A. P. F. Marão +1

We present the perturbation equations in an embedded four space-time from the linear Nash-Greene fluctuations of background metric. In the context of a five-dimensional bulk, we sh…
