cds-question@unistra.frsupernovaeastronomical-modelschemical-abundancesstellar-agesvisible-astronomyType Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections based on light-curve properties. One factor behind these corrections is dust extinction, which is accounted for in the color-luminosity relation of the standardization. This relation is usually assumed to be universal, which can potentially introduce systematics into the standardization. The 'mass step' observed for SN Ia Hubble residuals has been suggested as one such systematic. We seek to obtain a more complete view of dust attenuation properties for a sample of 162 SN Ia host galaxies and to probe their link to the mass step. We inferred attenuation laws toward hosts from both global and local (4 kpc) Dark Energy Survey photometry and composite stellar population model fits. We recovered a relation between the optical depth and the attenuation slope, best explained by differing star-to-dust geometry for different galaxy orientations, which is significantly different from the optical depth and extinction slope relation observed directly for SNe. We obtain a large variation of attenuation slopes and confirm these change with host properties, such as the stellar mass and age, meaning a universal SN Ia correction should ideally not be assumed. Analyzing the cosmological standardization, we find evidence for a mass step and a two-dimensional 'dust step', both more pronounced for red SNe. Although comparable, the two steps are not found to be completely analogous. We conclude that host galaxy dust data cannot fully account for the mass step, using either an alternative SN standardization with extinction proxied by host attenuation or a dust-step approach.2023A&A...680A..56Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/680/A56CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/874/150 : The first 3yrs of DES-SN (DES-SN3YR) (Brout+, 2019)J/MNRAS/494/4426 : Effect of host galaxies on SN luminosity (Smith+, 2020)J/MNRAS/495/4040 : SN host galaxies in Dark Energy Survey I (Wiseman+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/680/A56https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/680/A56http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/680/A56https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/680/A56https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/680/A56http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/680/A56GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/680/A56/tablee1 (Best-fit results for the DES host galaxy fits with DECam griz global and local photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/680/A56/tablee1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/680/A56/tablee1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/680/A56/tablee1?GETtext/xml+votable180.050000true53.6462169444-28.12700111110.0055555555555555565/4422 8983 6/17669 17671 17677 17679-17680 17682-17683 17686 17692-17694 17712 17735 17741 17746-17748 17750-17753 17756 35382 35385 35387-35390 35473-35475 35481 35927 35956 35959 36098 36104 36106-36107 36128https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/680/A56?format=asciiOpticaldefaultJ/A+A/680/A56/tablee1Best-fit results for the DES host galaxy fits with DECam griz global and local photometrySimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
