cds-question@unistra.frgalaxiesvisible-astronomyspectroscopyphotometryredshiftedtwo-color-diagramsWe use multiwavelength data from the Galaxy And Mass Assembly (GAMA) survey to explore the cause of red optical colours in nearby (0.002<z<0.06) spiral galaxies. We show that the colours of red spiral galaxies are a direct consequence of some environment-related mechanism(s) that has removed dust and gas, leading to a lower star formation rate. We conclude that this process acts on long time-scales (several Gyr) due to a lack of morphological transformation associated with the transition in optical colour. The specific star formation rate (sSFR) and dust-to-stellar mass ratio of red spiral galaxies is found to be statistically lower than blue spiral galaxies. On the other hand, red spirals are on average 0.9dex more massive, and reside in environments 2.6 times denser than their blue counterparts. We find no evidence of excessive nuclear activity, or higher inclination angles to support these as the major causes for the red optical colours seen in >~47 per cent of all spirals in our sample. Furthermore, for a small subsample of our spiral galaxies that are detected in HI, we find that the SFR of gas-rich red spiral galaxies is lower by ~1dex than their blue counterparts.2020MNRAS.491..398Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/491/398CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/474/3875 : Galaxy And Mass Assembly (GAMA): DR3 (Baldry+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/491/398https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/491/398http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/491/398https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/491/398https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/491/398http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/491/398GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/491/398/table2 (The sky coordinates, z, (g-r) colour, ALFALFA ID and HI mass of spiral galaxies used in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/491/398/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/491/398/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/491/398/table2?GETtext/xml+votable180.050000true178.5090.7850.0055555555555555564/1365 1622 1642 1685 1706 5/1024-1026 5459 5468-5469 6397-6399 6479 6483-6484 6486-6487 6492-6494 6501 6512-6514 6562-6563 6572 6737 6739 6828 6830 6912 10239 6/4108 4112 4128 8200 8202-8203 8224 21830-21831 21861 21884 25567 25583 25587 25911 25914-25915 25927 25929-25931 25940 25942-25943 25980 26001 26013 26015 26060 26064 26296 26947 26953 26992-26993 26995-26997 27273-27276 27278-27279 27290 27318 27324 27652-27654 27656 40950-40951 40953 40955 45050-45051https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/491/398?format=asciiOpticaldefaultJ/MNRAS/491/398/table2The sky coordinates, z, (g-r) colour, ALFALFA ID and HI mass of spiral galaxies used in this workzRedshiftsrc.redshiftfloatSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
