cds-question@unistra.frsupernovaeultraviolet-astronomyWe present constraints on Type Ia supernovae (SNe Ia) progenitors through an analysis of the environments found at the explosion sites of 102 events within star-forming host galaxies. H{alpha} and Galaxy Evolution Explorer near-ultraviolet (UV) images are used to trace on-going and recent star formation (SF), while broad-band B, R, J, K imaging is also analysed. Using pixel statistics we find that SNe Ia show the lowest degree of association with H{alpha} emission of all supernova (SN) types. It is also found that they do not trace near-UV emission. As the latter traces SF on time-scales less than 100Myr, this rules out any extreme 'prompt' delay times as the dominant progenitor channel of SNe Ia. SNe Ia best trace the B-band light distribution of their host galaxies. This implies that the population within star-forming galaxies is dominated by relatively young progenitors. Splitting SNe by their (B-V) colours at maximum light, 'redder' events show a higher degree of association with HII regions and are found more centrally within hosts. We discuss possible explanations of this result in terms of line-of-sight extinction and progenitor effects. No evidence for correlations between SN stretch and environment properties is observed.2015MNRAS.448..732Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/732CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/448/732https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/732http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/732https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/732https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/732http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/732GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/448/732/sn (SN and host galaxy parameters (table 1) and environment statistical analyses values (table A1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/732/sn?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/732/sn?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/732/sn?GETtext/xml+votable180.050000true196.471666737.60194440.0055555555555555566/611 697 3446 4105 4312 4439 4577 4719 4993 5006 5342 5593 5639 5975 5980 6936 7166 7241 7488 7659 7674 7696 7715 7783 8064 8085 8169 8927 10191 10531 10563 10628 10817 10819 11158 11496 15955 16194 17736 17741 18214 18895 20014 20875 21872 22399 23013 23078 25078-25079 25333 25344 25491 25513 25635 25769-25770 25788 25889 25960 26068 26271 26297 26336 26390 27348 27367 27373 27426 27512 27604 27757 27857 27918 27945 28035 28167 28224 28299 28498 28529 28579 28593 28619 31230 35844 36131 36287 36450 39863 40337 40379 40458 43245 43262 43713 44915https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/448/732?format=asciiUVdefaultJ/MNRAS/448/732/snSN and host galaxy parameters (table 1) and environment statistical analyses values (table A1)recnoRecord number assigned by the VizieR team.
