In recent years, the Hubble tension has emerged as one of the most perplexing enigmas within the realm of cosmology[1]. This incongruity suggests the tantalizing prospect of new physics beyond the standard ΛCDM model, leading to the proposal of diverse extended cosmological models. At the same time, there is a pressing demand for novel cosmological tools to mediate the Hubble tension. The gravitational-wave(GW) standard siren has been put forth as a promising cosmological probe for resolving the Hubble tension, provided that the redshift of the GW source is known, as exemplified in ref. [2].

We give a brief review on the recent development of gravitational waves in extra-dimensional theories of gravity.Studying extra-dimensional theories with gravitational waves provides a new way to constrain extra dimensions.After a flash look at the history of gravitational waves and a brief introduction to several major extra-dimensional theories, we focus on the sources and spectra of gravitational waves in extra-dimensional theories.It is shown that one can impose limits on the size of extra dimensions and the curvature of the universe by researching the propagations of gravitational waves and the corresponding electromagnetic waves.Since gravitational waves can propagate throughout the bulk, how the amplitude of gravitational waves decreases determines the number of extra dimensions for some models.In addition, we also briefly present some other characteristics of gravitational waves in extra-dimensional theories.

The exact metric of a Schwarzschild black hole in the true radiation gauge was recently reported. In this work, we base on this gravity and calculate the gravitational deflection of relativistic massive particles up to the fourth post-Minkowskian order. It is found that the result is consistent with the previous formulations for both the case of dropping the fourth-order contribution and the case of light deflection. Our result might be helpful for future high-accuracy observations.

The field of experimental gravitational waves(GWs)started in 1960s with Joseph Weber and his resonant bars which monitor GW-excited vibration of elastic bodies.In 2015,laser-interferometric detectors,as Weber bars’descendant,made the first detection of GWs in the kilo-Hertz band,and opened up a completely new window to observe the gravitational Universe[1].GWs from coalescing black holes and neutron stars are cataloged.

The Newtonian gravitational constant G is determined by means of the swing time method at the Cave Laboratory of Center for gravitational Experiment of Huazhong University of Science and Technology. The result value of G is (6.669 0±0.001 6)×10 -11 m 3·kg -1 ·s -2 , which is consistent with the CODATA value of G obtained by Cohen and Taylor in 3σ .

Gabbard et al.have demonstrated that convolutional neural networks can achieve the sensitivity of matched filtering in the recognization of the gravitational-wave signals with high efficiency[Phys.Rev.Lett.120,141103(2018)].In this work we show that their model can be optimized for better accuracy.The convolutional neural networks typically have alternating convolutional layers and max pooling layers,followed by a small number of fully connected layers.We increase the stride in the max pooling layer by 1,followed by a dropout layer to alleviate overfitting in the original model.We find that these optimizations can effectively increase the area under the receiver operating characteristic curve for various tests on the same dataset.

Derivations in this letter by the post-Newtonian approximation method given in Ref. [1] are the unified expressions of the gravitational acceleration for Einstein’s theory and Brans-Dicke theory in the gravitational field surrounding a spherically symmetric static mass distribution. The expressions are applied respectively to the gravitational fields of the Earth and the Jupiter, and the corrective value of the acceleration of a particle in the fields is estimated.
