cds-question@unistra.frgalaxy-clustersx-ray-sourcesgalaxy-classification-systemsThis is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the SRG/eROSITA Final Equatorial-Depth Survey (eFEDS). We aim to investigate scaling relations between observable cluster properties and mass, and to study the radial X-ray profiles of a large sample of optically selected clusters. We analyze a sample of 997 CAMIRA clusters with richness N>15 and redshifts of 0.1<z<1.3. Using bolometric luminosities derived from count rates and a weak-lensing mass calibration, we study the L-M and N-M scaling relations through stacking analysis, while accounting for selection effects and redshift evolution. We also compare clusters with and without X-ray counterparts in the eFEDS catalog in terms of their scaling relations and surface brightness profiles. The best-fit L-M slope (1.56^+0.14^_-0.12_) is slightly steeper than the self-similar prediction, yet remains consistent with our previous findings. The N-M slope (0.766^+0.070^_-0.060_) broadly agrees with theoretical expectations and other optical samples. The data do not require any additional redshift evolution beyond the standard self-similar scaling, although current constraints on evolution remain weak. X-ray detected clusters exhibit a marginally steeper L-M slope, higher central surface brightness, and more centrally concentrated X-ray profiles than undetected systems. Our results highlight systematic differences in the X-ray properties between optically and X-ray selected cluster samples. This study extends scaling relation analyses into lower mass and luminosity regimes, demonstrating the value of combining deep X-ray and optical surveys like eROSITA and Subaru HSC.2026A&A...710A.202Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/710/A202CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/444/147 : Richness of galaxy clusters (Oguri, 2014)J/PASJ/70/S20 : HSC Wide S16A cluster catalog (Oguri+, 2018)J/A+A/661/A1 : The eFEDS X-ray catalogs (V7.4) (Brunner+, 2022)J/A+A/661/A3 : eFEDS counterparts to point-like sources (Salvato+, 2022)J/A+A/661/A4 : eFEDS optical cluster and group catalog (Klein+, 2022)J/A+A/661/A5 : The eFEDS AGN catalog (Liu+, 2022)J/A+A/661/A7 : X-ray properties of eFEDS clusters and groups (Bahar+, 2022)J/A+A/661/A10 : eFEDS galaxy clusters and groups in disguise (Bulbul+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/710/A202https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/710/A202http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/710/A202https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/710/A202https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/710/A202http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/710/A202GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/710/A202/table1 (CAMIRA clusters in the eFEDS field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/710/A202/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/710/A202/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/710/A202/table1?GETtext/xml+votable180.050000true127.96343.27690.0055555555555555564/256 1365 1707 5/1028 1032 5459 5468-5469 5471 6819-6820 6822-6826 6834 6840 10239 6/4116-4118 4120-4121 4132-4134 4136-4138 4140 4160 4224 21831 21860-21861 21863 21881 21883 27269 27271 27273 27275 27286-27287 27308 27310-27311 27342 27364-27366 27368-27370 40950-40951 40955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/710/A202?format=asciiX-rayOpticaldefaultJ/A+A/710/A202/table1CAMIRA clusters in the eFEDS fieldrecnoRecord number assigned by the VizieR team.
