Description
We present a preliminary comparison of two samples of galaxy clusters detected using different observational techniques. We consider shear-selected galaxy clusters from the HSC survey and X-ray selected galaxy clusters from the eFEDS field, which was observed by eROSITA. The former cluster detection technique is purely gravitational and is insensitive to complicated baryon physics, while the latter cluster detection technique is possible thanks to the free-free and line emission of the intra-cluster medium. Both galaxy cluster samples are selected from the same approximately 40 square degrees sky area. The primary aim is to examine the physical differences between these galaxy cluster samples and their selection functions.
