Abstract

{In this paper, we use large scale structure observations to test the redshift dependence of cosmic distance duality relation (CDDR), }, with and , being the luminosity and angular diameter distances, respectively. In order to perform the test, the following data set are considered: strong lensing systems and galaxy cluster measurements (gas mass fractions). No specific cosmological model is adopted, only a flat universe is assumed. { By considering two parametrizations, It is observed that the CDDR remain redshift independent within which is in full agreement with other recent tests involving cosmological data}. It is worth to comment that our results are independent of the baryon budget of galaxy clusters.
