Abstract With the advent of gravitational-wave astronomy marked by the aLIGO GW150914 and GW151226 observations, a measurement of the cosmological speed of gravity will likely soon be realised. We show that a confirmation of equality to the speed of light as indicated by indirect Galactic observations will have important consequences for a very large class of alternative explanations of the late-time accelerated expansion of our Universe. It will break the dark degeneracy of self-accelerated… Expand

Fate of Large-Scale Structure in Modified Gravity After GW170817 and GRB170817A.
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. Expand
Cosmological Backgrounds of Gravitational Waves
Gravitational wave observations have a great potential for probing cosmology. Here we concentrate on the early universe, and review proposed sources that can lead to cosmological backgrounds of… Expand
Non-trivial gravitational waves and structure formation phenomenology from dark energy
The detection of the GW170817/GRB170817A event improved the constraints on the propagation speed of gravitational waves, thus placing possible variations caused by dark energy under restraint. For… Expand
Dark Energy in Light of Multi-Messenger Gravitational-Wave Astronomy
Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and the fundamental properties of gravity. We review the different ways in which GWs can be used to test gravity… Expand
Direct detection of gravitational waves can measure the time variation of the Planck mass
The recent discovery of a $\gamma$-ray counterpart to a gravitational wave (GW) event has put extremely stringent constraints on the speed of gravitational waves at the present epoch. In turn, these… Expand
Self-accelerating universe in scalar-tensor theories after GW170817
The recent simultaneous detection of gravitational waves and a gamma-ray burst from a neutron star merger significantly shrank the space of viable scalar-tensor theories by demanding that the speed… Expand
Testing modified gravity at cosmological distances with LISA standard sirens
Modifications of General Relativity leave their imprint both on the cosmic expansion history through a non-trivial dark energy equation of state, and on the evolution of cosmological perturbations in… Expand

The recent observation of the the gravitational wave event GW170817 and of its electromagnetic counterpart GRB170817A, from a binary neutron star merger, has established that the speed of… Expand
Astrophysical Gravitational Waves in Conformal Gravity
We investigate the gravitational radiation from binary systems in conformal gravity (CG) and massive conformal gravity (MCG). CG might explain observed galaxy rotation curves without dark matter, and… Expand

TLDR
An overview of recent developments in modified gravity theories including f(R) gravity, braneworld gravity, Horndeski theory and massive/bigravity theory is given and how to test modifications of gravity on cosmological scales is discussed. Expand
Confirmation of general relativity on large scales from weak lensing and galaxy velocities
TLDR
A test of the applicability of general relativity on cosmological length scales using a quantity that combines measures of large-scale gravitational lensing, galaxy clustering and structure growth rate, reports that EG = 0.39 ± 0.06 on length scales of tens of megaparsecs, in agreement with the general relativistic prediction.

Probing gravity at cosmological scales by measurements which test the relationship between gravitational lensing and matter overdensity.
TLDR
Planned surveys will be able to measure E(G), an observational quantity whose expectation value is equal to the ratio of the Laplacian of the Newtonian potentials to the peculiar velocity divergence, to percent accuracy. Expand
Anisotropic stress as a signature of nonstandard propagation of gravitational waves.
TLDR
It is shown that in cosmological solutions of very general classes of models extending gravity-all scalar-tensor theories, Einstein-aether models, and bimetric massive gravity-a direct correspondence exists between perfect fluids apparently carrying anisotropic stress and a modification in the propagation of gravitational waves.

No-go theorems for generalized chameleon field theories.
TLDR
It is proved two theorems limiting its cosmological impact: the Compton wavelength of such a scalar can be at most ~/= 1 MPc at the present cosmic density, which restricts its impact to nonlinear scales, and the conformal factor relating Einstein- and Jordan-frame scale factors is essentially constant over the last Hubble time, which precludes the possibility of self-acceleration.
