However, studies of LSBGs in deep photometric surveys are often hindered by a lack of distance estimates. In this work, we present a new catalogue of 479 LSBGs, identified in deep optical imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). These galaxies are found across a range of environments, from the field to groups. Many are likely to be ultra-diffuse galaxies (UDGs). We see clear evidence for a bimodal population in colour-Sersic index space, and split our sample into red and blue LSBG populations. We estimate environmental densities for a sub-sample of 215 sources by statistically associating them with nearby spectroscopic galaxies from the overlapping GAMA spectroscopic survey. We find that the blue LSBGs are statistically consistent with being spatially randomized with respect to local spectroscopic galaxies, implying they exist predominantly in low-density environments. However, the red LSBG population is significantly spatially correlated with local structure. We find that 26+/-5 per cent of isolated, local LSBGs belong to the red population, which we interpret as quiescent. This indicates that high environmental density plays a dominant, but not exclusive, role in producing quiescent LSBGs. Our analysis method may prove to be very useful, given the large samples of LSB galaxies without distance information expected from e.g. the Vera C. Rubin observatory (aka LSST), especially in combination with upcoming comprehensive wide-field spectroscopic surveys.2021MNRAS.500.2049Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/500/2049CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/500/2049https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/500/2049http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/500/2049https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/500/2049https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/500/2049http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/500/2049GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/500/2049/table1 (Source catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/500/2049/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/500/2049/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/500/2049/table1?GETtext/xml+votable180.050000true149.2038494-1.76712310.0055555555555555565/2048 5463 6399 6483 6486 6488-6490 6543 6554 6565 6567 6569 6576 6740 6806 6808-6809 6811 6/4096 4099 4101-4102 4104 4108-4110 4114-4115 21837-21838 21841 21843-21845 21847 21851 21875-21877 25593 25595 25911 25915-25916 25919 25929 25936 25939-25940 25942-25943 25951 25965 25967 25969-25970 25972 25991 25996 25999 26001-26006 26008 26010-26013 26022 26032-26033 26049-26051 26054 26167 26171 26195 26198 26210-26211 26220 26222 26254-26255 26258-26259 26264 26266 26282-26286 26288-26290 26312 26951 26956-26957 26964-26966 26968 26970-26971 26983 26992 26994 27191 27197-27199 27205 27211-27212 27214-27216 27218-27219 27228 27230 27242-27243 27248 27250-27251 27257-27258 27260 27277-27279 27281 27283-27285 27288-27290 27292 27300 27302 27304 27306-27307 27311 27322 27324 27327-27330 27332-27333 27345 27370 27648-27650 27652-27654 27656-27657 31402 40957 40959 45054-45055https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/500/2049?format=asciiOpticaldefaultJ/MNRAS/500/2049/table1Source cataloguerecnoRecord number assigned by the VizieR team.
