Nonlinear Matter Power Spectrum from relativistic $N$-body Simulations: $\hat{I}{›}_{\mathrm{s}}$CDM versus $\hat{I}›$CDM

Özgür Akarsu, Eleonora Di Valentino, Jiří Vyskočil +3

We present relativistic $N$-body simulations of a $\hat{I}{›}_{\mathrm{s}}$CDM - sign-switching cosmological constant (CC) - scenario under general relativity and compare its nonlinear matter p…
