The Cosmological Principle (CP) -- the notion that Universe is spatially isotropic and homogeneous on large scales underlies a century of progress in cosmology. It conventionally formulated through Friedmann-Lema\^itre-Robertson-Walker (FLRW) cosmologies as spacetime metric, culminates successful highly predictive $\Lambda$-Cold-Dark-Matter ($\Lambda$CDM) model. Yet, tensions have emerged within $\Lambda$CDM model, most notably statistically significant discrepancy value Hubble constant,...
A design study is currently in progress for a third generation gravitational-wave (GW) detector called Einstein Telescope (ET). An important kind of source ET will be the inspiral and merger binary neutron stars (BNS) up to $z \sim 2$. If BNS mergers are progenitors short-hard $\gamma$-ray bursts, then some fraction them seen both electromagnetically through GW, so that luminosity distance redshift can determined separately. property these `standard sirens' they \emph{self-calibrating}:...

This can be separated into two kinds: hessence state ${\ensuremath{\phi}}_{1}^{2}>{\ensuremath{\phi}}_{2}^{2}$, hantom model with ${\ensuremath{\phi}}_{1}^{2}<{\ensuremath{\phi}}_{2}^{2}$. We discuss evolution these models in...

As an extension of our previous work [J.Qiao, T.Zhu, W.Zhao & A.Wang, arXiv:1909.03815], in this article, we calculate the effects parity violation on gravitational-wave (GW) waveforms during their propagation most general parity-violating gravities, including Chern-Simons modified gravity, ghost-free scalar-tensor symmetric teleparallel equivalence GR theory, Ho\v{r}ava-Lifshitz gravity and so on. For purpose, consider GWs generated by coalescence compact binaries concentrate imprints GWs....
We report the results of testing gravitational-wave birefringence using largest population events currently available. Gravitational-wave birefringence, which can arise from effective field theory extension general relativity, occurs when parity symmetry is broken, causing left- and right-handed polarizations to propagate following different equations motion. perform Bayesian inference on 94 reported by 4th-Open Catalog (4-OGC) a parity-violating waveform. find no evidence for violation...
High-order spatial derivatives are of crucial importance for constructing the low energy effective action a Lorentz or parity violating theory quantum gravity. One example is Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz gravity, in which one has to consider at least sixth-order gravitational order make power-counting renormalizable. In this paper, we and effects on propagation GWs due fifth derivatives, respectively. For purpose calculate corresponding waveforms produced by coalescence...
The examination of parity symmetry in gravitational interactions has drawn increasing attention. Although Einstein’s General Relativity is parity-conserved, numerous theories parity-violating (PV) gravity different frameworks have recently been proposed for motivations. In this review, we briefly summarize the recent progress these theories, and focus on observable effects PV terms waves (GWs), which are mainly reflected difference between left-hand right-hand polarization modes.

Abstract We revisit the gravitational lensing of light or waves by a Schwarzschild black hole in geometric optics. Rather than focusing on single massless particle, we investigate collective behavior congruence rays, described geodesic deviation equation (GDE). By projecting GDE onto Newman-Penrose tetrad, decouple and find an analytical Dyson-like series solution weak deflection thin lens limits. Using this solution, analyze evolution cross-sectional area axis ratio. Finally, reproduce...
Abstract Scalar-tensor gravity, exemplified by Brans-Dicke (BD) introduces additional scalar polarization modes that contribute radiation alongside tensor modes. We conduct a comprehensive analysis of how gravitational wave generation and propagation effects under gravity are encoded into the astrophysical stochastic background (AGWB). perform end-to-end analyses realistic populations simulated coalescing binary systems to generate AGWB mock data with third-generation detectors conducted...
Measurement of the pulsar timing residuals provides a direct way to detect relic gravitational waves at frequency $f\sim 1/{\rm yr}$. In this paper, we investigate constraints on inflationary parameters, tensor-to-scalar ratio $r$ and tensor spectral index $n_t$, by current future Pulsar Timing Arrays (PTAs). We find that Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China planned Square Kilometer Array (SKA) projects have fairly strong abilities test phantom-like models....
In this paper, we study the effects of parity violation on non-Gaussianities primordial gravitational waves in framework Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz theory gravity, which high-order spatial derivative operators, including ones violating parity, generically appear. By calculating three-point function, find that leading-order contributions to come from usual second-order terms, produce same bispectrum as found general relativity. The $n$th terms are always suppressed by a...

According to kg-day live data, we placed...
Screened modified gravity (SMG) is a kind of scalar-tensor theory with screening mechanisms, which can suppress the fifth force in dense regions and allow theories to evade solar system laboratory tests. In this paper, we investigate how mechanisms SMG affect gravitational radiation damping effects, calculate detail rate energy loss due emission tensor scalar radiations, derive their contributions change orbital period binary system.

The current observations on the gravitational-wave (GW) bursts by LIGO have already placed various constraints alternative gravity. In this paper, we investigate possible bounds which could be Brans-Dicke using GW detection from inspiralling compact binaries with proposed Einstein Telescope, a third-generation detector. We first calculate details waveforms lowest post-Newtonian...
Abstract Einstein's general relativity, as the most successful theory of gravity, is one cornerstones modern physics. However, experimental tests for gravity in high energy region are limited. The emerging gravitational-wave astronomy has opened an avenue probing fundamental properties a strong and dynamical field, particular, regime. In this work, we test parity conservation with gravitational waves. If symmetry broken, left- right-handed modes waves would follow different equations motion,...
