cds-question@unistra.frsupernovaegalaxiesvisible-astronomyh-alpha-photometryWe compare the radial locations of 178 core-collapse supernovae (CCSNe) to the R-band and H{alpha} light distributions of their host galaxies. When the galaxies are split into "disturbed" and "undisturbed" categories, a striking difference emerges. The disturbed galaxies have a central excess of CCSNe and this excess is almost completely dominated by supernovae of types Ib, Ic, and Ib/c, whereas type II supernovae dominate in all other environments. The difference cannot easily be explained by metallicity or extinction effects, and thus we propose that this is direct evidence for a stellar initial mass function that is strongly weighted toward high-mass stars, specifically in the central regions of disturbed galaxies.2010ApJ...717..342Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/717/342CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)II/256 : Sternberg Supernova Catalogue, 2004 version (Tsvetkov+, 2004)J/ApJS/197/20 : Relativistic EOS for core-collapse SN simulations (Shen+,J/MNRAS/416/3138 : SN 2009jf light curves (Valenti+, 2011)J/ApJ/708/661 : SDSS-II SN Survey: SNe II-P (D'Andrea+, 2010)J/A+A/508/371 : UBVRIJHK observations of SN 2007gr (Hunter+, 2009)J/MNRAS/394/2266 : SN 2005cs one-year photometry (Pastorello+, 2009)J/ApJ/687/1201 : SN and LGRB locations in their host galaxies (Kelly+, 2008)J/MNRAS/372/1315 : UBVRI photometry of SN 2004et (Sahu+, 2006)J/PASP/115/1280 : Classifications of SN host galaxies (van den Bergh+, 2003)http://www.cbat.eps.harvard.edu/lists/Supernovae.html : IAU list of SNehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/717/342https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/717/342http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/717/342https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/717/342https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/717/342http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/717/342GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/717/342/sample (Host galaxy sample used in this analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/717/342/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/717/342/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/717/342/sample?GETtext/xml+votable180.050000true20.55041670.95583330.0055555555555555566/611 1006 1601 2372 3446 3862 3906 3909 3929 4178 4704 5028 5148 5190 5200 5244 5342 5399 5589 5593 5654 5715 5751 5793 5797 5966 5978 5995 5999 6013 6034 6098 6347 6411 6615 7240 7386 7659 7896 7980 8042 8106 8173 8195 8196 8225 8256 8922 9437 10380 10381 10475 10595 10628 10637 10739 10892 10900 10905 10927 10935 10991 11027 11041 11173 11197 11246 11247 11392 11394 11460 11914 11944 14851 15593 15847 15955 16120 16194 16197 17688 17747 17761 17780 18013 18809 18895 19710 20000 20722 20875 21198 22721 22751 23528 25079 25344 25599 25788 25889 25960 25999 26068 26161 26175 26234 26303 26330 27043 27334 27426 27604 27712 27736 27741 27828 27861 28023 28123 28146 28167 28213 28348 28496 28521 28593 28619 30970 31882 36081 36785 36793 36820 38907 39863 40410 44026https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/717/342?format=asciiOpticaldefaultJ/ApJ/717/342/sampleHost galaxy sample used in this analysisrecnoRecord number assigned by the VizieR team.
