Nonlinear Matter Power Spectrum from relativistic $N$ -body Simulations: $Λ_{s}$ CDM versus $Λ$ CDM

Özgür Akarsu, Eleonora Di Valentino, Jiří Vyskočil +3

We present relativistic $N$ -body simulations of a $Λ_{s}$ CDM - sign-switching cosmological constant (CC) - scenario under general relativity and compare its nonlinear matter po…

Dynamical dark energy with AdS-to-dS and dS-to-dS transitions: Implications for the $H_{0}$ tension

Özgür Akarsu, Leandros Perivolaropoulos, Anna Tsikoundoura +2

We investigate the dynamics and cosmological implications of dark energy (DE), modeled as a scalar field with a hyperbolic tangent potential that induces a smooth shift in the effe…
