内容記述 | We revisit the concept of turnaround radius in cosmology, in the context of modified gravity. While preliminary analyses were limited to scalar-tensor/F(R) gravity, we extend the definition and the study of this quantity to a much broader class of theories including also quantum R^2 gravity. The turnaround radius is computed in terms of the parameters of the theory, and it is shown that a deviation not larger than 10% of this quantity from its value in Einstein’s theory could constrain the model parameters and even rule out some current theories. | |||||
