Abstract:
We analyze 143 Type Ia supernovae (SNe Ia) observed in H band
(1.6-1.8µm) and find that SNe Ia are intrinsically brighter in
H band with increasing host galaxy stellar mass. We find that SNeIa
in galaxies more massive than 1010.43M☉ are 0.13±0.04mag
brighter in H than SNe Ia in less massive galaxies. The same set of
SNe Ia observed at optical wavelengths, after width-color-luminosity
corrections, exhibit a 0.10±0.03mag offset in the Hubble residuals.
We observe an outlier population (|ΔHmax|>0.5mag) in the
H band and show that removing the outlier population moves the mass
threshold to 1010.65M☉ and reduces the step in H band to
0.08±0.04mag, but the equivalent optical mass step is increased to
0.13±0.04mag. We conclude that the outliers do not drive the
brightness-host-mass correlation. Less massive galaxies preferentially
host more higher-stretch SNe Ia, which are intrinsically brighter and
bluer. It is only after correction for width-luminosity and
color-luminosity relationships that SNe Ia have brighter optical
Hubble residuals in more massive galaxies. Thus, finding that SNe Ia
are intrinsically brighter in H in more massive galaxies is an
opposite correlation to the intrinsic (pre-width-luminosity
correction) optical brightness. If dust and the treatment of intrinsic
color variation were the main driver of the host galaxy mass
correlation, we would not expect a correlation of brighter H-band
SNeIa in more massive galaxies.
