Constraints on Baryon Density from the Effective Optical Depth of High-Redshift Quasars
Wen-Fei Liu, Yuan-Bo Xie, Zhi-E Liu +4
We present constraints on the baryonic matter density parameter, , within the framework of the CDM model. Our analysis utilizes observational data on the effective optical…

Test of the cosmic distance duality relation for arbitrary spatial curvature
Jin Qin, Fulvio Melia, Tong-Jie Zhang
The cosmic distance duality relation (CDDR), eta(z)=(1+z)^2 d_A(z)/d_L(z)=1, is one of the most fundamental and crucial formulae in cosmology. This relation couples the luminosity…

Assessing Cosmic Acceleration with the Alcock-Paczynski Effect in the SDSS-IV Quasar Catalog
Fulvio Melia, Jin Qin, Tong-Jie Zhang
The geometry of the Universe may be probed using the Alcock-Paczynski (AP) effect, in which the observed redshift size of a spherical distribution of sources relative to its angula…
