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, $\hat{I}{\text{c◯}}_b$, within the framework of the $\hat{I}›$CDM model. Our analysis utilizes observational data on the effective optica…
