Description
The eFEDS survey is a proof-of-concept mini-survey designed to demonstrate the survey science capabilities of eROSITA onboard SRG. It covers an area of 140 square degrees and more than 500 galaxy clusters have been detected out to a redshift of 1.3. The HSC-SSP S19A data release covers around 510 square degrees, containing approximately 36 million galaxies. This galaxy catalogue is used to construct a sample of more than 180 shear-selected galaxy clusters. The common area of both surveys covers about 90 square degrees, making it an ideal region to investigate the wavelength selection effects in identifying galaxy clusters. In this talk, we aim to present and discuss the X-ray properties of shear-selected clusters compared to X-ray-detected cluster samples. Our results show that the luminosity-mass relation of both samples is similar, and the distribution of the cluster dynamical properties of both samples is also indistinguishable.
