Optical Extragalactic Emission-line Objects VII/178 ivo://CDS.VizieR/VII/178 CDS Hewitt A. Burbidge G. 2017-12-18T07:56:47Z 2004-07-24T22:47:42Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr active-galactic-nuclei A catalog of 935 galaxies which have optical properties similar to those of QSOs is given. A subsidiary table of cross-identifications enables the reader to relate the name of a given object to its coordinate name. Most of the objects appear to be nonstellar. The majority, more than 700, have redshifts z<=0.2, and have mostly been classified as Seyfert galaxies, N systems, or radio galaxies. The Hubble diagram for all of the objects with z<=0.2 is shown. The redshift distribution peaks at z ~ 0.025, but there are about 200 powerful radio galaxies in the extended tail of the distribution which have z>0.2. There is a separate and distinct peak in the redshift distribution at z=0.06. 1991ApJS...75..297H https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/178 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VII/178 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VII/178 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VII/178 https://vizier.cds.unistra.fr/viz-bin/votable?-source=VII/178 https://vizier.iucaa.in/viz-bin/votable?-source=VII/178 http://vizieridia.saao.ac.za/viz-bin/votable?-source=VII/178 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table VII/178/catalog (*Emission-line objects similar to QSOs) https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/178/catalog? https://vizier.iucaa.in/viz-bin/conesearch/VII/178/catalog? http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/178/catalog?
