cds-question@unistra.frgalaxy-clustersspectroscopyLuminous Compact Blue Galaxies (LCBGs) are an extreme star-bursting population of galaxies that were far more common at earlier epochs than today. Based on spectroscopic and photometric measurements of LCBGs in massive (M>10^15^M_{sun}_), intermediate redshift (0.5<z<0.9) galaxy clusters, we present their rest-frame properties including star formation rate, dynamical mass, size, luminosity, and metallicity. The appearance of these small, compact galaxies in clusters at intermediate redshift helps explain the observed redshift evolution in the size-luminosity relationship among cluster galaxies. In addition, we find the rest-frame properties of LCBGs appearing in galaxy clusters are indistinguishable from field LCBGs at the same redshift. Up to 35% of the LCBGs show significant discrepancies between optical and infrared indicators of star formation, suggesting that star formation occurs in obscured regions. Nonetheless, the star formation for LCBGs shows a decrease toward the center of the galaxy clusters. Based on their position and velocity, we estimate that up to 10% of cluster LCBGs are likely to merge with another cluster galaxy. Finally, the observed properties and distributions of the LCBGs in these clusters lead us to conclude that we are witnessing the quenching of the progenitors of dwarf elliptical galaxies that dominate the number density of present-epoch galaxy clusters.2016ApJ...817...87Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/817/87CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/741/98 : Spectroscopy of galaxy clusters to find LCBGsJ/ApJ/708/1076 : The WHIQII survey: compact blue galaxies (Tollerud+, 2010)J/ApJ/692/556 : Star forming galaxy templates (Rieke+, 2009)J/ApJ/617/240 : Oxygen abundances in the GOODS-North fieldJ/AJ/131/332 : Velocities of individual stars in NGC 205 (Geha+, 2006)J/MNRAS/417/1996 : Gas properties in emission-line galaxies (Jaffe+, 2011)J/MNRAS/335/10 : H{alpha} survey of Abell 1689 (Balogh+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/817/87https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/817/87http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/817/87https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/817/87https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/817/87http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/817/87GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/817/87/table1 (Summary of cluster observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/817/87/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/817/87/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/817/87/table1?GETtext/xml+votable180.050000true73.545-3.0141670.005555555555555556Cone search capability for table J/ApJ/817/87/table2 (Measured properties of LCBGs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/817/87/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/817/87/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/817/87/table2?GETtext/xml+votable180.050000true4.61847616.43771060.0055555555555555566/9831 9842 10389 10391 19848 22915 27009https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/817/87?format=asciiOpticaldefaultJ/ApJ/817/87/table1Summary of cluster observationsrecnoRecord number assigned by the VizieR team.
