cds-question@unistra.frgalaxiessupernovaeType Ia supernovae (SNe Ia) have been used as excellent standardizable candles for measuring cosmic expansion, but their progenitors are still elusive. Here, we report that the spectral diversity of SNe Ia is tied to their birthplace environments. We found that those with high-velocity ejecta are substantially more concentrated in the inner and brighter regions of their host galaxies than are normal-velocity SNe Ia. Furthermore, the former tend to inhabit larger and more luminous hosts. These results suggest that high-velocity SNe Ia likely originate from relatively younger and more metal-rich progenitors than do normal-velocity SNe Ia and are restricted to galaxies with substantial chemical evolution.2013Sci...340..170Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Sci/340.170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/689/377 : SNe Ia as NIR standard candles from PAIRITELJ/MNRAS/389/1577 : UBVRI absolute magnitudes of Type Ia SNe (Takanashi+, 2008)J/ApJ/699/L139 : Spectral parameters of SNe Ia (Wang+, 2009)J/ApJ/707/1449 : Local hosts of SNe Ia (Neill+, 2009)J/ApJ/721/1608 : Absolute UV magnitudes of type Ia SNe (Brown+, 2010)J/ApJ/722/566 : SDSS-II SN survey host galaxies of SNe Ia (Lampeitl+, 2010)J/ApJS/190/418 : Light curves for 165 SNe Ia (Ganeshalingam+, 2010)J/AJ/139/519 : Carnegie supernova project.
