cds-question@unistra.frsurveysgalaxiesvisible-astronomysloan-photometryredshiftedWe present a catalogue of isolated field elliptical (IfE) galaxies drawn from the W1 field of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). 228 IfEs were identified from a flux-limited (r<21.8) galaxy catalogue which corresponds to a density of 3 IfE/sq.deg. For comparison we consider a sample of elliptical galaxies living in dense environments, based on identification of the brightest cluster galaxies (BGCs) in the same survey. Using the same dataset for the comparison sample ensures a uniform selection, including in the redshift range as IfEs (i.e. 0.1<z<0.9 ). A comparison of elliptical galaxies in different environments reveals that IfEs and BCGs have similar behaviours in their colours, star formation activities, and scaling relations of mass-size and size-luminosity. IfEs and BCGs have similar slopes in the scaling relations with respect to cluster ellipticals within the -24<=Mr<=-22 magnitude and 10.2<log(M*/M_{sun})<=12.0 mass ranges. Three IfEs identified in this study can be associated with fossil groups found in the same survey area which gives clues for future studies.2022PASA...39...31Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PASA/39.31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/317 : The CFHTLS Survey (T0007 release) (Hudelot+ 2012)https://www.cfht.hawaii.edu/Science/CFHTLS/T0007 : CFHTLS T0007 Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/PASA/39.31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/PASA/39.31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/PASA/39.31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/PASA/39.31https://vizier.iucaa.in/viz-bin/votable?-source=J/other/PASA/39.31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/PASA/39.31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/PASA/39.31/tablea1 (Catalogue of isolated field elliptical galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/PASA/39.31/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/PASA/39.31/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/PASA/39.31/tablea1?GETtext/xml+votable180.050000true30.7562771-10.92275520.0055555555555555564/1104 2298 5/4373 4375 4420-4422 4424-4425 9198 6/17489-17491 17497 17525 17692 17694 17705 17708 17712-17714 36605-36606 36750 36786 36798https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/PASA/39.31?format=asciiOpticaldefaultJ/other/PASA/39.31/tablea1Catalogue of isolated field elliptical galaxiesrecnoRecord number assigned by the VizieR team.
