Testing cosmic anisotropy with the Combo correlation of gamma-ray bursts
Dong Zhao, Hao-Ran Duan, Jun-Qing Xia
We employ the sample of 244 gamma-ray bursts (GRBs; i.e., C244) with the Combo correlation to test cosmic anisotropy. Meanwhile, the Pantheon sample is introduced to verify whether…

Testing Gravity from Cosmic Shear Measurements
Jiachen Bai, Jun-Qing Xia, Gong-Bo Zhao
In this work, we perform a detailed analysis to constrain the Hu-Sawicki \(f(R)\) gravity model, using cosmic shear data from three prominent Stage-III weak lensing surveys: DES-Y3…
