# No slip gravity

@article{Linder2018NoSG, title={No slip gravity}, author={Eric V. Linder}, journal={Journal of Cosmology and Astroparticle Physics}, year={2018}, volume={2018}, pages={005 - 005} }

A subclass of the Horndeski modified gravity theory we call No Slip Gravity has particularly interesting properties: 1) a speed of gravitational wave propagation equal to the speed of light, 2) equality between the effective gravitational coupling strengths to matter and light, Gmatter and Glight, hence no slip between the metric potentials, yet difference from Newton's constant, and 3) suppressed growth to give better agreement with galaxy clustering observations. We explore the…

It is shown that the dark-matter growth rate must now be at least as fast as in general relativity (GR), with the possible exception of that beyond the Horndeski model, and if there is any scale dependence at all in the slip parameter, it is such that it takes the GR value at large scales.

It is shown that the detection of an electromagnetic counterpart to the gravitational-wave signal from the merger of two neutron stars allows for stringent constraints on general scalar-tensor and vector-Tensor theories, while allowing for an independent bound on the graviton mass in bimetric theories of gravity.
