Bias of reconstructing the dark energy equation of state from the Pad cosmography
Yang Liu, Zhengxiang Li, Hongwei Yu +1
Pad cosmography has been widely used to probe the cosmic evolution and to investigate the nature of dark energy. In this paper, we find that the Pad approxima…
Conserved charges in Chern-Simons modified theory and memory effects
Shaoqi Hou, Tao Zhu, Zong-Hong Zhu
In this work, conserved charges and fluxes at the future null infinity are determined in the asymptotically flat spacetime for Chern-Simons modified gravity. The flux-balance laws…
Narrowband searches for continuous and long-duration transient gravitational waves from known pulsars in the LIGO-Virgo third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1658
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully-coherent s…
Tests of General Relativity with GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1682
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensiti…
Gravitational wave memory of the binary black hole events in GWTC-2
Zhi-Chao Zhao, Xiaolin Liu, Zhoujian Cao +1
Gravitational wave (GW) memory is an important prediction of general relativity. Existing works on the GW memory detection focus on the waveform analysis. It is hard for waveform a…
The effective dynamics of weak coupling loop quantum gravity
Gaoping Long, Yongge Ma
By taking the limit that Newton's Gravitational constant tends to zero, the weak coupling loop quantum gravity can be formulated as a gauge theory instead of the original…
Gravitational lensing of Continuous Gravitational Waves
Marek Biesiada, Sreekanth Harikumar
Continuous gravitational waves are analogous to monochromatic light and therefore could be used to detect wave effects like interference or diffraction. This would be possible with…
Method of distinguishing between black holes and wormholes
Wei Hong, Jun Tao, Tong-Jie Zhang
Beginning with a brief review of the regular space-time with asymptotically Minkowski core, we can consider two copies of the space-time connected through a short-throat wormhole w…
Stochastic gravitational wave background due to gravitational wave memory
Zhi-Chao Zhao, Zhoujian Cao
Gravitational wave memory is an important prediction of general relativity, which has not been detected yet. Amounts of memory events can form a stochastic gravitational wave memor…
Study of acceleration measurement in gravitational wave detection
Junlang Li, Teng Zhang
Position-meter and speed-meter interferometers have been analysed for detecting gravitational waves. We introduce the concept of acceleration measurement in comparison with positio…
Strong cosmic censorship in near-extremal Kerr-Sen-de Sitter spacetime
Ming Zhang, Jie Jiang
We first calculate equations of motion for particles in the Kerr-Sen-de Sitter black hole spacetime. Then in the eikonal regime, we analytically obtain the quasi-normal resonant mo…
Twisted geometry coherent states in all dimensional loop quantum gravity: I. Construction and Peakedness properties
Gaoping Long, Xiangdong Zhang, Cong Zhang
A new family of coherent states for all dimensional loop quantum gravity are proposed, which is based on the generalized twisted geometry parametrization of the phase space of $SO(…
Black Hole Zeroth Law in Horndeski Gravity
Aofei Sang, Jie Jiang
The four laws of black hole mechanics have been put forward for a long time. However, the zeroth law, which states that the surface gravity of a stationary black hole is a constant…
All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…
Gravitational memory effects in Chern-Simons modified gravity
Shaoqi Hou, Tao Zhu, Zong-Hong Zhu
The gravitational memory effects of Chern-Simons modified gravity are considered in the asymptotically flat spacetime. If the Chern-Simons scalar does not directly couple with the…
Generalized proof of the linearized second law in general quadric corrected Einstein-Maxwell gravity
Xin-Yang Wang, Jie Jiang
Although the entropy of black holes in any diffeomorphism invariant theory of gravity can be expressed as the Wald entropy, the issue of whether the entropy always obeys the second…
Gedanken experiments at high-order approximation: Kerr black hole cannot be overspun
Aofei Sang, Jie Jiang
Sorce and Wald proposed a new version of gedanken experiments to examine the weak cosmic censorship conjecture (WCCC) in Kerr-Newmann black holes. However, their discussion only in…
First Law of Black Hole in the Gravitational Electromagnetic System
Jie Jiang, Aofei Sang, Ming Zhang
After considering the quantum corrections of Einstein-Maxwell theory, the effective theory will contain some higher-curvature terms and nonminimally coupled electromagnetic fields.…
Photon emissions from near-horizon extremal and near-extremal Kerr equatorial emitters
Haopeng Yan, Zezhou Hu, Minyong Guo +1
We consider isotropic and monochromatic photon emissions from equatorial emitters moving along future-directed timelike geodesics in the near-horizon extremal Kerr (NHEK) and near-…
Light rings and long-lived modes in quasi-black hole spacetimes
Minyong Guo, Zhen Zhong, Jinguang Wang +1
It has been argued that ultracompact objects, which possess light rings but no horizons, may be unstable against gravitational perturbations. To test this conjecture, we revisit th…

Kai Shi, Yu Tian, Xiaoning Wu +2
We provide a proof of the necessary and sufficient condition on the profile of the temperature, chemical potential, and angular velocity for a charged perfect fluid in dynamic equi…
