Testing X-ray Measurements of Galaxy Cluster Gas Mass Fraction Using the Cosmic Distance-Duality Relation

Xin Wang, Xiao-Lei Meng, Y. F. Huang +1

We propose a consistency test of some recent X-ray gas mass fraction ($f_{\mathrm{gas}}$) measurements in galaxy clusters, using the cosmic distance-duality relation, $η_{\rm{theory}}=…
