Decoupling perturbations from background in gravity: the square-root correction and the impact on the tension
Chunyu Li, Xin Ren, Yuhang Yang +2
We investigate a perturbation-level modification of symmetric teleparallel gravity of the form and assess its potential to ease the tension. The square-…
Quantum Gravity Meets DESI: Dynamical Dark Energy in Light of the Trans-Planckian Censorship Conjecture
Chunyu Li, Junkai Wang, Dongdong Zhang +2
Recent DESI DR2 observations indicate that dark energy has crossed from phantom to quintessence regime, a behavior known as the quintom-B realization. In this work we constrain dyn…
Gaussian-process reconstructions and model building of quintom dark energy from latest cosmological observations
Yuhang Yang, Qingqing Wang, Chunyu Li +4
In this article we use the latest cosmological observations, including SNe, BAO, CC and RSD, to reconstruct the cosmological evolution via the Gaussian process. At the background l…
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…
