cds-question@unistra.frgalaxy-clusterssurveysx-ray-sourcesScaling relations link the physical properties of clusters at cosmic scales. They are used to probe the evolution of large-scale structure, estimate observables of clusters, and constrain cosmological parameters through cluster counts. We investigate the scaling relations between X-ray observables of the clusters detected in the eFEDS field using Spectrum-Roentgen-Gamma/eROSITA observations taking into account the selection effects and the distributions of observables with cosmic time. We extract X-ray observables (Lx, Lbol, T, Mgas, Yx) within R500 for the sample of 542 clusters in the eFEDS field. By applying detection and extent likelihood cuts, we construct a subsample of 265 clusters with a contamination level of <10% (including AGNs and spurious fluctuations) to be used in our scaling relations analysis. The selection function based on the state-of-the-art simulations of the eROSITA sky is fully accounted for in our work. We provide the X-ray observables in the core- included <R500 and core-excised 0.15*R500-R500 apertures for 542 galaxy clusters and groups detected in the eFEDS field. Additionally, we present our best-fit results for the normalization, slope, redshift evolution, and intrinsic scatter parameters of the X-ray scaling relations between Lx-T, Lx- Mgas, Lx-Yx, Lbol-T, Lbol-Mgas, Lbol-Yx, and Mgas-T. We find that the best-fit slopes significantly deviate from the self-similar model at a >4sigma confidence level, but our results are nevertheless in good agreement with the simulations including non-gravitational physics, and the recent results that take into account selection effects. The strong deviations we find from the self-similar scenario indicate that the non-gravitational effects play an important role in shaping the observed physical state of clusters. This work extends the scaling relations to the low-mass, low-luminosity galaxy cluster and group regime using eFEDS observations, demonstrating the ability of eROSITA to measure emission from the intracluster medium out to R500 with survey-depth exposures and constrain the scaling relations in a wide mass-luminosity-redshift range.2022A&A...661A...7Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/661/A7CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/661/A1 : The eFEDS X-ray catalogs (V7.4) (Brunner+, 2022)J/A+A/661/A2 : Galaxy clusters and groups in eFEDS (Liu+, 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/A8 : eFEDS catalogue of variable X-ray sources (Boller+, 2022)J/A+A/661/A10 : eFEDS galaxy clusters and groups in disguise (Bulbul+, 2022)J/A+A/661/A23 : Exoplanet X-ray irradiation & evaporation rates (Foster+, 2022)J/A+A/661/A24 : Corona-chromosphere connection (Fuhrmeister+, 2022)J/A+A/661/A29 : First eROSITA study of nearby M dwarfs (Magaudda+, 2022)J/A+A/661/A34 : eta Cha cluster eROSITA X-ray scan (Robrade+, 2022)J/A+A/661/A35 : eROSITA study of 47 Tuc globular cluster (Saeedi+, 2022)J/A+A/661/A38 : SRG/ART-XC 1st year all-sky X-ray survey (Pavlinsky+, 2022)J/A+A/661/A40 : eRASS1 X-ray sources Sco-Cen members (Schmitt+, 2022)J/A+A/661/A44 : A first eROSITA view of ultracool dwarfs (Stelzer+, 2022)https://erosita.mpe.mpg.de/edr/eROSITAObservations/Catalogues/ :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/661/A7https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/661/A7http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/661/A7https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/661/A7https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/661/A7http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/661/A7GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/661/A7/table2 (X-ray observable measurements of eFEDS clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/661/A7/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/661/A7/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/661/A7/table2?GETtext/xml+votable180.050000true126.6108-0.57480.0055555555555555564/256 1367 1707 5/1028-1029 1032 5459-5460 5462-5463 5465 6819 6822 6827 6842 10239 6/4120-4122 4124 4134-4138 4160-4161 4224 21830-21831 21833 21835 21844 21846-21847 21859 21869 21972-21973 27269 27271 27274-27275 27280 27282-27283 27286 27292 27294-27298 27300 27302-27305 27307 27336 27338-27339 27360-27362 27364 27372 40951 40953-40955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/661/A7?format=asciiX-raydefaultJ/A+A/661/A7/table1Electron density model parameters of eFEDS clustersE_epsilonPlus side error bar on epsilonstat.error;stat.maxfloatbetabeta parameter of Vikhlinin06 model (1)stat.param;meta.modelledfloate_betaMinus side error bar on betastat.errorfloatE_betaPlus side error bar on betastat.error;stat.maxfloatalphaalpha parameter of Vikhlinin06 model (1)stat.param;meta.modelledfloate_alphaMinus side error bar on alphastat.error;pos.eq.rafloatE_alphaPlus side error bar on alphastat.error;stat.maxfloatSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
