cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryredshiftedDespite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H_0_) in the Hubble-Lemaitre law remain unknown. To break the current impasse, it is necessary to develop as many independent techniques as possible, such as the use of Type II supernovae (SNe II). The goal of this paper is to demonstrate the utility of SNe II for deriving accurate extragalactic distances, which will be an asset for the next generation of telescopes where more-distant SNe II will be discovered. More specifically, we present a sample from the Dark Energy Survey Supernova Program (DES-SN) consisting of 15 SNe II with photometric and spectroscopic information spanning a redshift range up to 0.35. Combining our DES SNe with publicly available samples, and using the standard candle method (SCM), we construct the largest available Hubble diagram with SNe II in the Hubble flow (70 SNe II) and find an observed dispersion of 0.27mag. We demonstrate that adding a colour term to the SN II standardization does not reduce the scatter in the Hubble diagram. Although SNe II are viable as distance indicators, this work points out important issues for improving their utility as independent extragalactic beacons: find new correlations, define a more standard subclass of SNe II, construct new SN II templates, and dedicate more observing time to high-redshift SNe II. Finally, for the first time, we perform simulations to estimate the redshift-dependent distance-modulus bias due to selection effects.2020MNRAS.495.4860Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/4860CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/874/150 : The first 3yrs of DES-SN (DES-SN3YR) (Brout+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/4860https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/4860http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/4860https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/4860https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/4860http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/4860GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/4860/tablea1 (Spectroscopically classified SNe II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4860/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4860/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4860/tablea1?GETtext/xml+votable180.050000true54.7225-28.77463890.005555555555555556Cone search capability for table J/MNRAS/495/4860/tabled1 (The supernova sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4860/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4860/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4860/tabled1?GETtext/xml+votable180.050000true39.246-5.35547220.0055555555555555565/8983 6/43 552 4182 4410 8306 12290 16652 17001 17669 17671 17677 17679 17683 17686 17689-17692 17694 17712 17745-17747 17750 17752 17812 17831 17836 17999 18023 18083 18405 18795 19097 19457 19584 19616 21148 23144 23190 24225 24873 25645 27258 27840 28346 29348 30034 30038 35388-35390 35473 35692 35927 35953 35956-35957 36098 36107 36210 36799 36811 36827 36908 38623 39108 40300 40527 40531 40819 40847 40939 45433 45711 46004 47028 47187 47564 49097https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/4860?format=asciiOpticalInfrareddefaultJ/MNRAS/495/4860/tablea1Spectroscopically classified SNe IISimbadNameSimbad column added by the CDSmeta.idcharnullableCommentsCommentsmeta.notecharrecnoRecord number assigned by the VizieR team.
