cds-question@unistra.frsupernovaeinfrared-photometryWe present a measurement of the Hubble constant (H0) using type Ia supernova (SNe Ia) in the near-infrared (NIR) from the recently updated sample of SNe Ia in nearby galaxies with distances measured via Cepheid period-luminosity relations by the SHOES project. We collect public near-infrared photometry of up to 19 calibrator SNe Ia and further 57 SNe Ia in the Hubble flow (z>0.01), and directly measure their peak magnitudes in the J and H band by Gaussian processes and spline interpolation. Calibrator peak magnitudes together with Cepheid-based distances are used to estimate the average absolute magnitude in each band, while Hubble-flow SNe are used to constrain the zero-point intercept of the magnitude-redshift relation. Our baseline result of H0 is 72.3+/-1.4 (stat) +/-1.4 (syst) km/s/Mpc in the J band and 72.3+/-1.3 (stat) +/-1.4 (syst) km/s/Mpc in the H band, where the systematic uncertainties include the standard deviation of up to 21 variations of the analysis, the 0.7% distance scale systematic from SHOES Cepheid anchors, a photometric zeropoint systematic, and a cosmic variance systematic. Our final measurement represents a measurement with a precision of 2.8% in both bands. Among all analysis variants the largest change in H0 comes from limiting the sample to those SNe from the CSP and CfA programmes, noteworthy because these are the best calibrated, yielding H0~75km/s/Mpc in both bands. We explore applying stretch and reddening corrections to standardize SN Ia NIR peak magnitudes, and we demonstrate they are still useful to reduce the absolute magnitude scatter improving its standardization, at least up to the H band. Based on our results, in order to improve the precision of the H0 measurement with SNe Ia in the NIR in the future, we would need to increase the number of calibrator SNe Ia, be able to extend the Hubble-Lemaitre diagram to higher redshift, and include standardization procedures to help reducing the NIR intrinsic scatter.2023A&A...679A..95Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/679/A95CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/679/A95https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/679/A95http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/679/A95https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/679/A95https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/679/A95http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/679/A95GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/679/A95/tablec1 (SNooPy maxmodel and EBVmodel2, only EBV parameter, template fitting results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/679/A95/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/679/A95/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/679/A95/tablec1?GETtext/xml+votable180.050000true56.1275-44.639830.0055555555555555566/732 1796 2311 2409 3393 4114 4577 5975 7523 7659 8267 8532 9098 9311 9533 9619 10218 10379 10438 10816 10984 11071 11434 11496 12455 12497 13907 16690 17152 17207 17818 18011 18214 19051 19227 19581 19624 20291 21857 22943 23013 23023 23219 23294 23349 24131 24152 25141 25333 25615 25769 25960 26584 27348 27470 27491 27738 28075 28148 28294 28353 28619 33228 34361 34531 36287 36805 36919 37299 37429 43339 44359 44660 44915 45418 46882https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/679/A95?format=asciiInfrareddefaultJ/A+A/679/A95/tablec1SNooPy maxmodel and EBVmodel2, only EBV parameter, template fitting resultsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
