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…

No Slip CMB
No Slip Gravity is a simple modified gravity theory with only one free function and the interesting characteristic that— unlike many modified gravity theories—it suppresses growth. This allows it to
Gravitational Wave Distances in Horndeski Cosmology
Gravitational wave propagation encounters a spacetime friction from a running Planck mass in modified gravity, causing the luminosity distance to deviate from that in general relativity (or given by

We systematically assess several limiting cases of modified gravity, where particular theoretical or observational conditions hold. This framework includes the well known scalar-tensor gravity and No

Gravitational-wave luminosity distance in modified gravity theories
In modified gravity theories, the luminosity distance for gravitational waves (GWs) is in general different from that for electromagnetic signals. This opens the possibility of model-independent
Gravity's islands: parametrizing Horndeski stability
Cosmic acceleration may be due to modified gravity, with effective field theory or property functions describing the theory. Connection to cosmological observations through practical parametrization
Modified gravity away from a ΛCDM background
Within the effective field theory approach to cosmic acceleration, the background expansion can be specified separately from the gravitational modifications. We explore the impact of modified gravity
Quantum gravity and gravitational-wave astronomy
We investigate possible signatures of quantum gravity which could be tested with current and future gravitational-wave (GW) observations. In particular, we analyze how quantum gravity can influence

TLDR
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.

We identify a scalar-tensor model embedded in the Horndeski action whose cosmological background and linear scalar fluctuations are degenerate with the concordance cosmology. The model admits a

TLDR
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.
