cds-question@unistra.frgalaxy-clustersredshiftedco-line-emissionThe results of a CO line survey in central cluster galaxies with cooling flows are presented. Cold molecular gas is detected with the IRAM 30m telescope, through CO(1-0) and CO(2-1) emission lines in 6-10 among 32 galaxies. The corresponding gas masses are between 3x10^8^ and 4x10^10^M_{sun}. These results are in agreement with recent CO detections by Edge (2001MNRAS.328..762E). A strong correlation between the CO emission and the H{alpha} luminosity is also confirmed. Cold gas exists in the center of cooling flow clusters and these detections may be interpreted as evidence of the long searched for very cold residual of the hot cooling gas.2003A&A...412..657Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/412/657CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/412/657https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/412/657http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/412/657https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/412/657https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/412/657http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/412/657GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/412/657/table1 (Sample of cooling flow clusters of galaxies observed with the IRAM 30m telescope.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/412/657/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/412/657/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/412/657/table1?GETtext/xml+votable180.050000true10.46-9.3030560.0055555555555555566/2432 5536 6611 8220 8268 8520 8526 9354 9468 9476 9664 10312 11672 14744 15112 17141 17237 17797 18437 19501 19608 19941 20079 20355 21766 22007 22577 23324 26848 28005 40615 40777https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/412/657?format=asciiOpticalRadiodefaultJ/A+A/412/657/table23Summary of observational data for the two runs (tables 2 and 3 of the paper)recnoRecord number assigned by the VizieR team.
