cds-question@unistra.frgalaxy-clusterssupernovaeWe used the Gaussian Mixture Brightest Cluster Galaxy catalogue and Sloan Digital Sky Survey-II supernovae data with redshifts measured by the Baryon Oscillation Spectroscopic Survey to identify 48 Type Ia supernovae (SNe Ia) residing in rich galaxy clusters and compare their properties with 1015 SNe Ia in the field. Their light curves were parametrized by the SALT2 model and the significance of the observed differences was assessed by a resampling technique. To test our samples and methods, we first looked for known differences between SNe Ia residing in active and passive galaxies. We confirm that passive galaxies host SNe Ia with smaller stretch, weaker colour-luminosity relation [{beta} of 2.54(22) against 3.35(14)], and that are ~ 0.1mag more luminous after stretch and colour corrections. We show that only 0.02 percent of random samples drawn from our set of SNe Ia in active galaxies can reach these values. Reported differences in the Hubble residuals scatter could not be detected, possibly due to the exclusion of outliers. We then show that, while most field and cluster SNe Ia properties are compatible at the current level, their stretch distributions are different (~3{sigma}): besides having a higher concentration of passive galaxies than the field, the cluster's passive galaxies host SNe Ia with an average stretch even smaller than those in field passive galaxies (at 95 percent confidence). We argue that the older age of passive galaxies in clusters is responsible for this effect since, as we show, old passive galaxies host SNe Ia with smaller stretch than young passive galaxies (~4{sigma}).2013MNRAS.434.1443Xhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/434/1443CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/135/348 : SDSS-II SNe survey: search and follow-up (Sako+, 2008)J/AJ/135/1766 : Sloan Digital Sky Survey-II supernova survey (Zheng+, 2008)J/AJ/136/2306 : SDSS-II Supernova survey, 2005 (Holtzman+, 2008)J/ApJ/713/1026 : SN Ia rate at redshift <~0.3 from SDSS-II (Dilday+, 2010)J/ApJS/185/32 : First-year SDSS-II SN results (Kessler+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/434/1443https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/434/1443http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/434/1443https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/434/1443https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/434/1443http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/434/1443GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/434/1443/tablea1 (All supernovae Ia in the cluster sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/434/1443/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/434/1443/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/434/1443/tablea1?GETtext/xml+votable180.050000true40.5608-0.86220.0055555555555555566/17727 17751-17753 17756 17764 17770 17826 17981 18008 18010 18019 18021 18026 18032 18069-18070 18072 18074 18077 18087 18686 18792 18800 18835 18839 18844 18854 18880 19049 19052 19054 19089 19097 19100 19121 30033 30036-30037https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/434/1443?format=asciiOpticaldefaultJ/MNRAS/434/1443/tablea1All supernovae Ia in the cluster sampleCID[822/20882] SN Ia's candidate ID <SDSS-II SN NNNNN> in Simbadmeta.id;meta.mainintprimaryRAJ2000[-90/90] SN right ascension (J2000.0)degpos.eq.ra;meta.mainDEJ2000SN declination (J2000.0)degpos.eq.dec;meta.mainzsn[0.1/0.44] Supernova redshift z_SN_src.redshift;pos.heliocentricfloatf_zsn[SPB] Typing kind (S=spectroscopic) (1)meta.codecharBCGidIdentifier (SDSS objID of its BCG) of the GMBCG cluster hosting the supernova (Hao et al. 2010, J/ApJS/191/254)meta.id.assocBCGDeltails of the GMBCG cluster hosting the supernova (Hao et al. 2010, J/ApJS/191/254)meta.ref.urlcharx1[-4/3] SALT2 'stretch' parameter x_1_ (4)stat.fit.paramfloate_x1rms uncertainty on x1stat.errorfloatc[-0.3/0.4] SALT2 'colour' parameter c (4)stat.fit.paramfloate_crms uncertainty on cstat.errorfloatHRHubble Residual obtained with the full sample (cluster + field) nuisance parameters (4)stat.fit.residualfloate_HRrms uncertainty on HRstat.errorfloatHost?
