Testing the cosmic distance duality with X-ray gas mass fraction and supernovae data

R. S. Goncalves, R. F. L. Holanda, J. S. Alcaniz

In this paper we discuss a new cosmological model-independent test for the cosmic distance duality relation (CDDR), $\eta =D_L(L)(1+z{)}^{-2}/D_A(z)=1$, where $D_A(z)$ and $D_{L}(…
