cds-question@unistra.frsupernovaeapparent-magnituderedshiftedWe present a novel technique for fitting restframe I-band light curves on a data set of 42 type Ia supernovae (SNe Ia). Using the result of the fit, we construct a Hubble diagram with 26 SNe from the subset at 0.01<z<0.1. Adding two SNe at z~0.5 yields results consistent with a flat Lambda-dominated "concordance universe'' (Omega_M_,Omega_Lambda_)=(0.25, 0.75). For one of these, SN 2000fr, new near infrared data are presented. The high redshift supernova NIR data are also used to test for systematic effects in the use of SNe Ia as distance estimators. A flat, Lambda=0, universe where the faintness of supernovae at z~0.5 is due to grey dust homogeneously distributed in the intergalactic medium is disfavoured based on the high-z Hubble diagram using this small data-set. However, the uncertainties are large and no firm conclusion may be drawn. We explore the possibility of setting limits on intergalactic dust based on B-I and B-V colour measurements, and conclude that about 20 well measured SNe are needed to give statistically significant results. We also show that the high redshift restframe I-band data points are better fit by light curve templates that show a prominent second peak, suggesting that they are not intrinsically underluminous.2005A&A...437..789Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/437/789CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/189 : Magnitude Observations of Type I Supernovae (Cadonau+ 1990)J/A+A/317/423 : Revised photometry of SNIa (Patat, 1997)J/ApJ/607/665 : Type Ia supernovae at z>1 discovered by HST (Riess+, 2004)J/ApJ/613/200 : Hubble Higher z Supernova Search, HHZSS (Strolger+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/437/789https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/437/789http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/437/789https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/437/789https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/437/789http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/437/789GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/437/789/table2 (*Results of the I-band light curve fit of 42 nearby supernovae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/437/789/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/437/789/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/437/789/table2?GETtext/xml+votable180.050000true170.058041713.005250.0055555555555555566/626 2227 2379 4719 5639 6178 7659 7923 8064 8763 10734 10817 10858 18206 18296 18895 19551 20353 23405 25078 25850 26268 27367 27728 27773 27945 28167 28299 31628 32129 32569 33839 35629 35844 36253 37580 38613 43827 43855 44000 44026 45983https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/437/789?format=asciiOpticaldefaultJ/A+A/437/789/table2*Results of the I-band light curve fit of 42 nearby supernovaerecnoRecord number assigned by the VizieR team.
