Abstract:
Type Ia Supernovae (SNe Ia) have been used as standardizable candles
in the optical wavelengths to measure distances with an accuracy of
∼7% out to redshift z∼1.5. There is evidence that in the near-infrared
(NIR) wavelengths SNe Ia are even better standard candles, however,
NIR observations are much more time-consuming.
We aim to test whether the NIR peak magnitudes could be accurately
estimated with only a single observation obtained close to maximum
light, provided that the time of B band maximum, the B-V color at
maximum and the optical stretch parameter are known.
We present multi-epoch UBVRI and single-epoch J and H photometric
observations of 16 SNe Ia in the redshift range z=0.037-0.183,
doubling the leverage of the current SN Ia NIR Hubble diagram and the
number of SNe beyond redshift 0.04. This sample was analyzed together
with 102 NIR and 458 optical light curves (LCs) of normal SNe Ia from
the literature. Results. The analysis of 45 NIR LCs with well-sampled
first maximum shows that a single template accurately describes the
LCs if its time axis is stretched with the optical stretch parameter.
This allows us to estimate the peak NIR magnitudes of SNe with only
few observations obtained within ten days from B-band maximum. The NIR
Hubble residuals show weak correlation with ΔM15 and the color
excess E(B-V), and for the first time we report a potential dependence
on the Jmax-Hmax color. With these corrections, the intrinsic NIR
luminosity scatter of SNe Ia is estimated to be ∼0.10mag, which is
smaller than what can be derived for a similarly heterogeneous sample
at optical wavelengths. Analysis of both NIR and optical data shows
that the dust extinction in the host galaxies corresponds to a low
RV~=1.8-1.9.
We conclude that SNe Ia are at least as good standard candles in the
NIR as in the optical and are potentially less affected by systematic
uncertainties. We extended the NIR SN Ia Hubble diagram to its
nonlinear part at z∼0.2 and confirmed that it is feasible to
accomplish this result with very modest sampling of the NIR LCs, if
complemented by well-sampled optical LCs. With future facilities it
will be possible to extend the NIR Hubble diagram beyond redshift
z~=1, and our results suggest that the most efficient way to achieve
this would be to obtain a single observation close to the NIR maximum.
