cds-question@unistra.frgalaxiesphotometryWe present a study of the nature of the blue early-type galaxies (BEGs) in the GOODS North and South fields using the GOODS archival HST ACS data. Using visual inspection, we have selected 58 BEGs and 113 normal red early-type galaxies (REGs) in the sample of 1949 galaxies with spectroscopic redshifts. We find that the BEGs are generally bluer, fainter, and less massive than the REGs, although a few BEGs are exceptionally bright and massive. The number fraction of BEGs to total early-type galaxies is almost constant (~0.3) at z<=1.1. In addition, we find that the sizes of the BEGs in a given redshift bin decrease as redshift decreases. The BEGs look similar to the REGs in the images and surface brightness profiles.2006ApJ...650..148Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/650/148CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)http://www.stsci.edu/ftp/science/goods/ : GOODS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/650/148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/650/148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/650/148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/650/148https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/650/148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/650/148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/650/148/table1 (Basic Properties of Blue Early-type Galaxies (BEGs))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/650/148/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/650/148/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/650/148/table1?GETtext/xml+votable180.050000true188.990083362.17352780.0055555555555555566/11252 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/650/148?format=asciidefaultJ/ApJ/650/148/table1Basic Properties of Blue Early-type Galaxies (BEGs)recnoRecord number assigned by the VizieR team.
