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

Özgür Akarsu, Eleonora Di Valentino, Jiří Vyskočil +3

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