cds-question@unistra.frgalaxy-clustersh-i-line-emissionredshiftedAccording to the cold dark matter (CDM) hierarchical clustering theory of galaxy and large-scale structure formation, there should be numerous low-mass dark matter haloes present in the Universe today. If these haloes contain sufficient stars, they should be detectable as low-luminosity stellar systems or dwarf galaxies. We have previously described a new detection method for faint low surface brightness objects and we have shown that there are relatively large numbers of very faint dwarf galaxies in the nearby Virgo cluster. In this paper, we present results from a similar survey carried out on the Millennium Galaxy strip (MGS, cat. <VII/240>), which runs along the celestial equator and samples a very different galaxy environment.2004MNRAS.352..478Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/352/478CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/240 : Millennium Galaxy Catalogue (Liske+, 2003)J/ApJS/81/5 : Green Bank neutral hydrogen survey (Schneider+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/352/478https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/352/478http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/352/478https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/352/478https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/352/478http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/352/478GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/352/478/table1 (Table of sure optical detections in the Millennium Galaxy strip (MGS))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/478/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/478/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/478/table1?GETtext/xml+votable180.050000true152.6750417-0.12766670.005555555555555556Cone search capability for table J/MNRAS/352/478/table2 (Table of detections in the UMa cluster)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/478/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/478/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/478/table2?GETtext/xml+votable180.050000true181.22545.126940.005555555555555556Cone search capability for table J/MNRAS/352/478/table3 (Table of unsure detections in the MGS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/478/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/478/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/478/table3?GETtext/xml+votable180.050000true152.10025-0.13713890.0055555555555555565/6490 6554 6/5592-5593 10921 10938-10939 10994 25919 25935 25945-25946 25957 25964 26005-26006 26009-26010 26020-26022 26025-26026 26196 26201-26202 26204 26213-26214 26255 26259 26261 26266 26277 26281-26282 26879 26943 26965 26969-26970 26981-26982 26985-26986 27027 27029-27030 27033-27034 27045-27046 27049-27050 27220 27222 27224 27226https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/352/478?format=asciiOpticalRadiodefaultJ/MNRAS/352/478/table1Table of sure optical detections in the Millennium Galaxy strip (MGS)ComGalaxy typecharBmagB magnitudemagfloatrecnoRecord number assigned by the VizieR team.
