Quasinormal modes of tensor perturbation in Kaluza-Klein black hole for Einstein-Gauss-Bonnet gravity
Li-Ming Cao, Liang-Bi Wu, Yaqi Zhao +1
In Einstein-Gauss-Bonnet gravity, we study the quasi-normal modes (QNMs) of the tensor perturbation for the so-called Maeda-Dadhich black hole which locally has a topology $\mathca…
The effective field theory approach to the strong coupling issue in gravity
Yu-Min Hu, Yaqi Zhao, Xin Ren +3
We investigate the scalar perturbations and the possible strong coupling issues of around a cosmological background, applying the effective field theory (EFT) approach. We r…
Quasinormal Modes in Noncommutative Schwarzschild black holes
Y. Zhao, Yifu Cai, S. Das +3
We investigate the quasinormal modes of a massless scalar field in a Schwarzschild black hole, which is deformed due to noncommutative corrections. We introduce the deformed Schwar…
Stochastic gravitational wave background from the collisions of dark matter halos
Qiming Yan, Xin Ren, Yaqi Zhao +1
We investigate the effect of the dark matter (DM) halos collisions, namely collisions of galaxies and galaxy clusters, through gravitational bremsstrahlung, on the stochastic gravi…
Quasinormal modes of black holes in f(T) gravity
Yaqi Zhao, Xin Ren, Amara Ilyas +2
We calculate the quasinormal modes (QNM) frequencies of a test massless scalar field and an electromagnetic field around static black holes in gravity. Focusing on quadratic…
Gaussian processes and effective field theory of gravity under the tension
Xin Ren, Sheng-Feng Yan, Yaqi Zhao +2
We consider the effective field theory formulation of torsional gravity in a cosmological framework to alter the background evolution. Then we use the latest measurement from…
Deflection angle and lensing signature of covariant f(T) gravity
Xin Ren, Yaqi Zhao, Emmanuel N. Saridakis +1
We calculate the deflection angle, as well as the positions and magnifications of the lensed images, in the case of covariant gravity. We first extract the spherically symme…
Testing the ALP-photon coupling with polarization measurements of Sagittarius A*
Guan-Wen Yuan, Ziqing Xia, Chengfeng Tang +5
Ultra-light bosons such as axions or axion-like particles (ALPs), are promising candidates to solve the dark matter problem. A unique way to detect such ALPs is to search for the p…
