Proposed new probe of modified gravity

Year: 2010

Type: article

Abstract: We suggest a new efficient way to constrain a certain class of large scale modifications of gravity. We show that the scale-free relation between density and size of dark matter halos, predicted within the ΛCDM model with Newtonian gravity, gets modified in a wide class of theories of modified gravity.
