We increase the number of LSB galaxies presented in Yagi et al. (2016ApJS..225...11Y, Cat. J/ApJS/225/11) by a factor of ~3 and report the discovery of 29 new ultradiffuse galaxies (UDGs). We compile the largest sample of UDGs with colours and structural parameters in the Coma cluster. While most UDGs lie along the red-sequence relation of the colour-magnitude diagram, ~16 per cent are outside (bluer or redder) the red-sequence region of Coma cluster galaxies. Our analyses show that there is no special distinction in the basic photometric parameters between UDGs and other LSB galaxies. We investigate the clustercentric colour distribution and find a remarkable transition at a projected radius of ~0.6Mpc. Within this cluster core region and relative to the red-sequence of galaxies, LSB galaxies are on average redder than co-spatial higher surface brightness galaxies at the 2{sigma} level, highlighting how vulnerable LSB galaxies are to the physical processes at play in the dense central region of the cluster. The position of the transition radius agrees with expectations from recent cosmological simulation of massive galaxy clusters within which ancient infalls are predicted to dominate the LSB galaxy population.2020MNRAS.496.3182Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/496/3182CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/225/11 : Subaru-UDGs in the Coma cluster (Yagi+, 2016)VII/42A : GMP catalogue: galaxies in the Coma cluster (Godwin+ 1983)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/496/3182https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/496/3182http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/496/3182https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/496/3182https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/496/3182http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/496/3182GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/496/3182/table2 (Catalogue of Coma cluster galaxies with structural parameters from GALFIT analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/3182/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/3182/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/3182/table2?GETtext/xml+votable180.050000true194.898427.95942110.005555555555555556Cone search capability for table J/MNRAS/496/3182/table3 (Newly discovered UDGs in the Coma cluster catalogued here for convenience)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/3182/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/3182/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/3182/table3?GETtext/xml+votable180.050000true195.2152428.87102890.0055555555555555565/2594 2600 6/10382 10404 28127 28149https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/496/3182?format=asciiOpticaldefaultJ/MNRAS/496/3182/table2Catalogue of Coma cluster galaxies with structural parameters from GALFIT analysisrecnoRecord number assigned by the VizieR team.
