Type Ia infrared data
Listed in IVOA Registry (Virtual Observatory)
We 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.
Description
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.
