Search for exotic gravitational wave signals beyond general relativity using deep learning
Yu-Xin Wang, Xiaotong Wei, Chun-Yue Li +6
The direct detection of gravitational waves by LIGO has confirmed general relativity (GR) and sparked rapid growth in gravitational wave (GW) astronomy. However, subtle post-Newton…
Gravitational wave constraints on non-birefringent dispersions of gravitational waves due to Lorentz violations with GWTC-3
Cheng Gong, Tao Zhu, Rui Niu +5
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry in the gravitational interaction. In…
Strongly lensed type Ia supernovae as a precise late-universe probe of measuring the Hubble constant and cosmic curvature
Jing-Zhao Qi, Yu Cui, Wei-Hong Hu +3
Strongly lensed type Ia supernovae (SNe Ia) are expected to have some advantages in measuring time delays of multiple images, and so they have a great potential to be developed int…
Cosmological model-independent measurement of cosmic curvature using distance sum rule with the help of gravitational waves
Yan-Jin Wang, Jing-Zhao Qi, Bo Wang +3
Although the cosmic curvature has been tightly constrained in the standard cosmological model using observations of cosmic microwave background anisotropies, it is still of great i…
Gravitational wave constraints on Lorentz and parity violations in gravity: high-order spatial derivative cases
Cheng Gong, Tao Zhu, Rui Niu +5
High-order spatial derivatives are of crucial importance for constructing the low energy effective action of a Lorentz or parity violating theory of quantum gravity. One example is…
No evidence for the evolution of mass density power-law index from strong gravitational lensing observation
Jing-Lei Cui, Hai-Li Li, Xin Zhang
In this paper, we consider the singular isothermal sphere lensing model that has a spherically symmetric power-law mass distribution . We investigate whether…
