Exploring the liminality: properties of haloes and subhaloes in borderlinef(R) gravity
2015
Monthly notices of the Royal Astronomical Society
We investigate the properties of dark matter haloes and subhaloes in an f(R) gravity model with |f_R0|=10^-6, using a very high-resolution N-body simulation. The model is a borderline between being cosmologically interesting and yet still consistent with current data. We find that the halo mass function in this model has a maximum 20 ΛCDM predictions between z=1 and z=0. Because of the chameleon mechanism which screens the deviation from standard gravity in dense environments, haloes more
