Searching for modified gravity: scale and redshift dependent constraints from galaxy peculiar velocities

We present measurements of both scale- and time-dependent deviations from the standard gravitational field equations. These late-time modifications are introduced separately for relativistic and non-relativistic particles, by way of the parameters G matter(k, z) and G light(k, z) using two bins in b...
