cds-question@unistra.frgalaxy-clustersx-ray-sourcesactive-galactic-nucleiWe present the first cosmological study of a sample of eROSITA clusters, which were identified in the eROSITA Final Equatorial Depth Survey (eFEDS). In a joint selection on X-ray and optical observables, the sample contains 455 clusters within a redshift range of 0.1 < z < 1.2, of which 177 systems are covered by the public data from the Hyper Suprime-Cam (HSC) survey that enables uniform weak-lensing cluster mass constraints. With minimal assumptions, at each cluster redshift we empirically model (1) the scaling relations between the cluster halo mass and the observables, which include the X-ray count rate, the optical richness, and the weak-lensing mass, and (2) the X-ray selection in terms of the completeness function C. Using the richness distribution of the clusters, we directly measure the X-ray completeness and adopt those measurements as informative priors for the parameters of C. In a blinded analysis, we obtain the cosmological constraints {omega}_m_=0.245^+0.048^_-0.058_, {sigma}_8_=0.833^+0.075^_-0.063_, and S_8_ = {sigma}_8_({omega}_m_/0.3)^0.3^ = 0.791^+0.028^_-0.031_ in a flat LCDM cosmology. Extending to a flat wCDM cosmology leads to the constraint on the equation of state parameter of the dark energy of w = -1.25 +/- 0.47. The eFEDS constraints are in good agreement with the results from the Planck mission, the galaxy-galaxy lensing and clustering analysis of the Dark Energy Survey, and the cluster abundance analysis of the SPT-SZ survey at a level of <~ 1{sigma}. With the empirical modelling, this work presents the first fully self-consistent cosmological constraints based on a synergy between wide-field X-ray and weak lensing surveys.2023MNRAS.522.1601Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/522/1601CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/488/739 : MARD-Y3 catalog (Klein+, 2019)J/MNRAS/474/3324 : Multicomponent matched filter test (Klein+, 2018)J/MNRAS/444/147 : Richness of galaxy clusters (Oguri, 2014)J/A+A/661/A1 : The eFEDS X-ray catalogs (V7.4) (Brunner+, 2022)J/A+A/661/A10 : eFEDS galaxy clusters and groups in disguise (Bulbul+, 2022)J/A+A/661/A11 : eFEDS.
