cds-question@unistra.frgalaxy-clustersx-ray-sourcesgalaxy-kinematicsWe use the ROSAT All-Sky Survey to study the X-ray properties of a sample of 625 groups and clusters of galaxies selected from the Sloan Digital Sky Survey. We stack clusters with similar velocity dispersions and investigate whether their average X-ray luminosities and surface brightness profiles vary with the radio activity level of their central galaxies. We find that at a given value of {sigma}, clusters with a central radio active galactic nucleus (AGN) have more concentrated X-ray surface brightness profiles, larger central galaxy masses and higher X-ray luminosities than clusters with radio-quiet central galaxies. The enhancement in X-ray luminosity is more than a factor of 2, is detected with better than 6{sigma} significance and cannot be explained by X-ray emission from the radio AGN itself. This difference is largely due to a subpopulation of radio-quiet, high velocity dispersion clusters with low-mass central galaxies. These clusters are underluminous at X-ray wavelengths when compared to otherwise similar clusters where the central galaxy is radio-loud, more massive, or both.2008MNRAS.389.1074Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/389/1074CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/130/968 : SDSS-C4 cluster catalog (Miller+, 2005)http://www.sdss.org : SDSS Home Pagehttp://www.ctio.noao.edu/~chrism/C4 : SDSS-C4 Galaxy Cluster Catalog Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/389/1074https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/389/1074http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/389/1074https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/389/1074https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/389/1074http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/389/1074GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/389/1074/tablea1 (*Clusters of galaxies individually detected in RASS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/389/1074/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/389/1074/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/389/1074/tablea1?GETtext/xml+votable180.050000true202.54301-2.105010.0055555555555555566/5030 5611 5618 5774 5825 5929 5933 5951 5974 5982 5996 6000-6002 6029 6039 6045 6056-6057 6067 6071 6076 6119 6223 6245 6247 6436 6473 6484 6499 6551 6554 7187 7198 7254 7266 7271 7301 7372 7536 8209 8212 9317 9333 9354 9443 9464 9468 9471 9504 9506 9508 9607 9793 9811 9815 9822 9833 9913 9943 9949 10063 10095 10146 10182 10194 10200 10211 10619 10645 10693 10718 10749 11005 11146 11159 11182 11240 11279 11287 11338 11341 11407 11426 11591 11597 11602 11809 11814 11907 11942 17237 17300 17303 17515 17810 17841 18006 18011 18016 18063 18073 18176 18367 18410-18411 18585 18588 18606-18607 19029 19114 19432 19993 21977 25852 25981-25982 26042 26053-26054 26185 26188 26197 26200 26206 26208 26302 26307 26313 26370 26432 26990 27060 27079 27081 27224-27225 27246 27279 27406 27417 27486 27652 27670-27671 27676 27685 27736 27777 31394 31401 31407https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/389/1074?format=asciiX-raydefaultJ/MNRAS/389/1074/tablea1*Clusters of galaxies individually detected in RASSrecnoRecord number assigned by the VizieR team.
