Non-linear dynamics of the minimal theory of massive gravity

We investigate cosmological signatures of the minimal theory massive gravity (MTMG). To this aim, we simulate normal branch MTMG by employing R AMSES N -body code and extending it with an effective gravitational constant G eff . implement environment-dependent as a function graviton mass local energy density predicted MTMG. find that halo profiles are not good probe for because deviations from general relativity (GR) quite small. Similarly, matter power spectra show only at percentage level. However, clear difference between GR in voids denser than GR. As measuring void is complex task observational point view, better would be abundances. In case, creates larger amount halos, while there suppression abundance small halos.
