This intermediate massive cluster ({sigma}=550km/s) is surrounded by a complex large-scale structure. Our work confirms the presence of UDGs in the cluster and in the large-scale structure that surrounds it, and it is the first detection of UDGs outside clusters. Approximately 50 per cent of the UDGs analysed in the selected area inhabit the cluster region (~11+/-5 per cent in the core and ~39+/-9 per cent in the outskirts), whereas the remaining UDGs are found outside the main cluster structure (~50+/-11 per cent). The colours and the spatial distribution of the UDGs within this large-scale structure are more similar to dwarf galaxies than to L* galaxies, suggesting that most UDGs could be bona fide dwarf galaxies.2017MNRAS.468..703Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/468/703CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/468/703https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/468/703http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/468/703https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/468/703https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/468/703http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/468/703GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/468/703/tableb1 (*Position and structural properties of the selected UDG candidates in the area surrounding Abell Cluster 168)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/468/703/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/468/703/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/468/703/tableb1?GETtext/xml+votable180.050000true19.99660.1540.0055555555555555565/4502 6/17997 18001-18003 18006 18012 18014 18033https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/468/703?format=asciiOpticaldefaultJ/MNRAS/468/703/tableb1*Position and structural properties of the selected UDG candidates in the area surrounding Abell Cluster 168nSersic indexstat.fit.paramfloate_nrms uncertainty on nstat.errorfloatrecnoRecord number assigned by the VizieR team.
