Restrictions on Extended Gravity at Galaxy Clusters Scales

Restrictions on Extended Gravity at Galaxy Clusters Scales

Following [1] we discuss the predictions of Starobinsky model of f(R)-gravity with vanishing cosmological constant at galaxy and galaxy clusters scales. As a result we demonstrate that at the current observational accuracy level there is no significant difference in cut-off radius values for Starobi...
