They were thought to form through tidal stripping of massive progenitors, until two isolated objects were discovered where massive galaxies performing the stripping could not be identified. By mining astronomical survey data, we have now found 195 compact elliptical galaxies in all types of environment. They all share similar dynamical and stellar population properties. Dynamical analysis for nonisolated galaxies demonstrates the feasibility of their ejection from host clusters and groups by three-body encounters, which is in agreement with numerical simulations. Hence, isolated compact elliptical and isolated quiescent dwarf galaxies are tidally stripped systems that ran away from their hosts.2015Sci...348..418Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Sci/348.418CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/540/A106 : SDSS-DR8 groups and clusters of galaxies (Tempel+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Sci/348.418https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Sci/348.418http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Sci/348.418https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Sci/348.418https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Sci/348.418http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Sci/348.418GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Sci/348.418/tables1 (Properties of 195 cEs and their host galaxies found in this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Sci/348.418/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Sci/348.418/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Sci/348.418/tables1?GETtext/xml+votable180.050000true237.290890.215620.0055555555555555566/4188 4195 4197 4772 4794 4797 4798 4799 4847 4988 4990 4992 5011 5029 5030 5487 5508 5530 5537 5558 5564 5607 5616 5618 5647 5656 5691 5692 5701 5786 5808 5854 5877 5923 5931 5974 5979 5982 6018 6057 6083 6213 6453 6473 8199 8208 8211 8213 8217 8230 8254 8263 8264 8268 8271 8288 8300 8341 8350 8351 8575 8668 8744 9228 9231 9235 9236 9243 9268 9368 9371 9448 9464 9466 9746 9824 9883 9903 9912 10524 10533 10586 10625 10664 10827 10846 10847 10871 10892 10923 10953 10959 10968 10969 10998 11044 11049 11051 11069 11186 11192 11281 11307 11405 11407 11433 11438 18003 18018 18019 18302 18411 19387 19432 19993 23192 25953 25972 25981 26001 26075 26097 26184 26284 26302 26307 26376 26454 26495 26985 27029 27076 27079 27123 27224 27248 27317 27454 27461 27474 27553 27595 27603 27606 27652 27738 27763 27813 27865 27914 27970 28166 28193 28208 31338 31354 31404 31407 31441 31458 31465 31466 31483 31545 32443 32486 32492https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Sci/348.418?format=asciiOpticalUVInfrareddefaultJ/other/Sci/348.418/tables1Properties of 195 cEs and their host galaxies found in this studySimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
