Are Type Ia Supernovae in Restframe $H$ Brighter in More Massive Galaxies?

Kara A. Ponder, W. Michael Wood-Vasey, Anja Weyant +5

We analyze 143 Type Ia supernovae (SNeIa) observed in $H$ band (1.6-1.8 $\mu$m) and find SNeIa are intrinsically brighter in $H$-band with increasing host galaxy stellar mass. We fin…
