New probe of modified gravity
arXiv:1001.0565 · doi:10.1016/j.physletb.2010.11.026
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 LambdaCDM model with Newtonian gravity, gets modified in a wide class of theories of modified gravity.
