Local host galaxy properties of type Ia supernovae from the Nearby SuperNovae Factory
Abstract
Type Ia supernovae are key tools to study accelerating expansion of the Universe. However despite active research, physics of such objects remain uncertain. To better understand potential systematics we investigate on local host galaxy properties. In this preliminary analysis, we find gas derived quantities such as metallicity and star formation rate compatible to those present in literature. Finally we show a relationship between SALT2 color and x_1 with star formation activity.
