<span style="background-color: rgb(255, 255, 255); text-transform: none;">In this talk, I will present recent results from the X-ray Cluster Science (XCS) collaboration, preparing for the X-ray support to upcoming cosmology surveys. First, I will present my
project on the X-ray properties of galaxy clusters observed by XMM-Newton, eROSITA, and the Dark Energy Survey. I will describe the cross-calibration of galaxy cluster temperatures and luminosities enabled by the open-source XGA and DAXA software packages,
applied to eROSITA data for the first time. I will then highlight complementary work , led by Paul Giles, characterising DES clusters in deep eROSITA survey regions. Finally, I will discuss the prospects for future X-ray–optical scaling relation studies with
the upcoming 4MOST spectroscopic survey. </span><br>
