Testing the cosmological principle with quasars
Shuangnan Chen, Xiaofeng Yang, Yunliang Ren +5
The inferred velocity is consistent at the 1.56 σ level with the value of 370 km/s from a purely kinematic interpretation of the CMB dipole. Based on the motion direction component…
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…
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…
The Dispersion Measure Contributions of the Cosmic Web
Charles R. H. Walker, Laura G. Spitler, Yin-Zhe Ma +3
The large-scale distribution of baryons is sensitive to gravitational collapse, mergers, and galactic feedback. Known as the Cosmic Web, its large-scale structure (LSS) can be clas…
CoLFI: Cosmological Likelihood-free Inference with Neural Density Estimators
Guo-Jian Wang, Cheng Cheng, Yin-Zhe Ma +3
In previous works, we proposed to estimate cosmological parameters with the artificial neural network (ANN) and the mixture density network (MDN). In this work, we propose an impro…
A measure of cosmological distance using the \civ\ Baldwin effect in quasars
L. Huang, H. Wang, Z. F. Gao +2
We use the anticorrelation between the equivalent width (EW) of the C\,\textsc{iv} 1549 Å emission line and the continuum luminosity in the quasars rest frame (Baldwin effect) to m…
