Testing Cosmic Distance Duality Relation and Transparency with DESI DR2
Xuwei Zhang, Xiaofeng Yang, Yunliang Ren +5
The Cosmic Distance Duality Relation (CDDR) is a fundamental principle of standard cosmology, linking luminosity (LD) and angular diameter distances (ADD). This work investigates t…
Testing the cosmological principle with quasars
Shuangnan Chen, Xiaofeng Yang, Yunliang Ren +5
The inferred velocity is consistent at the 1.56 Ï level with the value of 370 km/s from a purely kinematic interpretation of the CMB dipole. Based on the motion direction componen…
Interacting dark energy constraints from Fermi GRBs and Pantheon+ SNe Ia with full GRB covariance
Jianfeng Meng, Xiaofeng Yang, Yunliang Ren +4
The standard CDM model faces long-standing theoretical and observational problems, such as the Hubble tension, which motivate extensions beyond CDM, including interacting d…
Measurement of the Weyl Potential Evolution and Statistic from KiDS-1000, BOSS and 2dFLenS
Xuwei Zhang, Ming Zhang, Yunliang Ren +1
A recently developed model-independent approach to measuring the Weyl potential has shown some tensions with CDM (Lambda Cold Dark Matter) in DES (Dark Energy Survey) Y3 data.…
Holographic dark energy in a coasting cosmology
Yunliang Ren, Xiaofeng Yang, Xuwei Zhang +5
Coasting cosmology offers an intriguing and straightforward framework for understanding the universe. In this work, we employ the Trans-Planckian Censorship Criterion (TCC) conject…
Reconstructing Barrow Holographic Dark Energy in Gravity and Cosmic Constraint
Xuwei Zhang, Xiaofeng Yang, Yunliang Ren +4
In this work, we reconstruct the cosmological evolution of Barrow Holographic Dark Energy (BHDE) within the framework of modified gravity . Working in the coincident gauge,…
