“…A number of recent works (see for instance, Zhao et al 2011;Yang et al 2019b;Zhang et al 2020;Wolf & Lagos 2020;Yang et al 2020b;Bachega et al 2020;Li et al 2020, and references therein) have illustrated the strength of GW detections by their ability to constrain different dark energy models. Next-generation GW detections also give us the scope to perform tests on theories of modified gravity by confronting the modified propagation of GWs across cosmological distances.…”

The Einstein Telescope and other third generation interferometric detectors of gravitational waves are projected to be operational post 2030. The cosmological signatures of gravitational waves would undoubtedly shed light on any departure from the current gravitational framework. We here confront a specific modified gravity model, the No Slip Gravity model, with forecast observations of gravitational waves. We compare the predicted constraints on the dark energy equation of state parameters $w_0^{}-w_a^{}$, between the modified gravity model and that of Einstein gravity. We show that the No Slip Gravity model mimics closely the constraints from the standard gravitational theory, and that the cosmological constraints are very similar. The use of spectroscopic redshifts, especially in the low–redshift regime, lead to significant improvements in the inferred parameter constraints. We test how well such a prospective gravitational wave dataset would function at testing such models, and find that there are significant degeneracies between the modified gravity model parameters, and the cosmological parameters that determine the distance, due to the gravitational wave dimming effect of the modified theory.

“…• In refs. [591][592][593][594][595][596][597][598][599][600], a series of analyses have been made for the cosmological parameter estimation in various dark en-120401-18 ergy models using the combination of GW and EM observations (e.g., CMB, BAO, and SN). These analyses show that standard sirens alone cannot provide very tight constraints on the cosmological parameters except H 0 , but the combination of GW and EM observations can effectively break the parameter degeneracies and thus greatly improve the constraint accuracies.…”

It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events has revealed the promising capability of constraining various aspects of cosmology, astronomy, and gravity. Due to the limited space in this review article, we will briefly summarize the recent progress over the past five years, but with a special focus on some of our own work for the Key Project "Physics associated with the gravitational waves" supported by the National Natural Science Foundation of China. In particular, (1) we have presented the mechanism of the gravitational-wave production during some physical processes of the early Universe, such as inflation, preheating and phase transition, and the cosmological implications of gravitational-wave measurements; (2) we have put constraints on the neutron star maximum mass according to GW170817 observations; (3) we have developed a numerical relativity algorithm based on the finite element method and a waveform model for the binary black hole coalescence along an eccentric orbit.

“…However, even so, only a small part of them (around 0.1%) have the detectable EM counterparts [46], and thus the application of bright sirens in cosmology has strong limitations. Furthermore, it has been shown in some works [38,39,42,50,66] that solely using GW bright sirens cannot tightly constrain the EoS of dark energy and the main role they play in cosmology is to help break the cosmological parameter degeneracies of other traditional observations.…”

Using the measurements of tidal deformations in the binary neutron star (BNS) coalescences can obtain the information of redshifts of gravitational wave (GW) sources, and thus actually the cosmic expansion history can be investigated by solely using such GW dark sirens. To do this, the key is to get large amounts of accurate GW data, which can be achieved by employing the third-generation (3G) GW detectors. In this paper, we wish to offer an answer to the question of whether the Hubble constant and the equation of state (EoS) of dark energy can be precisely measured by solely using GW dark sirens. We find that in the era of 3G GW detectors O(10 5 )-O(10 6 ) dark siren data (with the tidal measurements) can be obtained in a several-year observation, and thus using only dark sirens can actually achieve the precision cosmology. Based on a network of 3G detectors, we obtain the constraint precisions of 0.1% and 0.6% for the Hubble constant H0 and the constant EoS of dark energy w, respectively; for a two-parameter EoS parametrization of dark energy, the precision of w0 is 1.4% and the error of wa is 0.086. We conclude that 3G GW detectors would lead to breakthroughs in solving the Hubble tension and revealing the nature of dark energy.
