An emulation-based model for the projected correlation function
Vetle A. Vikenes, Cheng-Zong Ruan, David F. Mota
Data from the ongoing \textit{Euclid} survey will map out billions of galaxies in the Universe, covering more than a third of the sky. This data will provide a wealth of informatio…
Non-linear matter power spectrum without screening dynamics modelling in gravity
Cheng-Zong Ruan, Tong-Jie Zhang, Bin Hu
Halo model is a physically intuitive method for modelling the non-linear power spectrum, especially for the alternatives to the standard CDM models. In this paper, we exam the S…
Using spatial curvature with HII galaxies and cosmic chronometers to explore the tension in
Cheng-Zong Ruan, Fulvio Melia, Yu Chen +1
We present a model-independent measurement of spatial curvature in the Friedmann-Lemaître-Robertson-Walker (FLRW) universe, based on observations of the Hubble parameter $H…
Model-independent Test of the Cosmic Distance Duality Relation
Cheng-Zong Ruan, Fulvio Melia, Tong-Jie Zhang
A validation of the cosmic distance duality (CDD) relation, eta(z)=(1+z)^2 d_A(z)/d_L(z)=1, coupling the luminosity (d_L) and angular-diameter (d_A) distances, is crucial because i…
