- Abstract: We investigate the turnaround radius in the spherical collapse model, both in General Relativity and in modified gravity, in particular f(R) scenarios. The phases of spherical collapse are marked by the non-linear density contrast in the instant of turnaround δt, and by the linear density contrast in the moment of collapse, δc. We find that the effective mass of the extra scalar degree of freedom which arises in modified gravity models has an impact on δt of up to ~16%, and that δc can increase by ~2.3%, for structures with mass of sime 1013 h−1 M⊙ at zsime 0. We also compute the turnaround radius, Rt, which in modified gravity models can increase by up to ~ 6%.
