Dependence of the analytical profile and its logarithmic slope on the cosmological parameters. Upper panels illustrate matter density across shells, normalized by the turnaround radius, at redshifts indicated by the titles. With different line colors we show how the profiles change for different values of Ω_m (assuming Ω_Λ = 0.7) and Ω_Λ (assuming Ω_m = 0.3). Bottom panels explore the change in the logarithmic slope of the respective density profiles.
