Type Ia supernovae (SN Ia) are central in measuring the accelerated expansion
of the Universe and the properties of the underlying dark energy.
Nearby SN Ia are compared with distant ones to establish the history of cosmic
expansion. In fact, current efforts in SN Ia cosmology are constrained by the
limited number of well-observed nearby SN Ia. A significantly improved sample
of nearby SN Ia, fully covering the space of Ia properties, is needed to
maximize the utility of high-redshift SN Ia. Our ongoing project at the CfA
has collected such a set of 150 CCD-based SN Ia, with some in UBVRI and some in UBVri, using the FLWO 1.2m telescope on Mt. Hopkins. We have now reduced this sample and present light curves of these SN Ia along with an analysis of their properties. In particular, we use our large nearby sample to explore the possible correlations of nearby SN Ia light-curve shape with host galaxy type.
The CfA Supernova program is supported in part by the National Science
Foundation through grant AST-0606772 to Harvard University.
