If it exists, a fifth force would influence the hot X-ray emitting gas filling the potential wells of galaxy clusters. However, it would not influence the clusters weak lensing signal. Therefore, by comparing X-ray and weak lensing profiles, one can place upper limits on the strength of a fifth force. Here we extend the techniques developed in Wilcox et al. 2015 & 2016 by applying them to the stacked profiles of hundreds of clusters detected by both the Dark Energy Survey and the XMM Cluster Survey.
