Chris Pritchet (UVIC) Title: The Supernova Legacy Survey - New results on the Nature of Type Ia Supernovae Abstract:The CFHT Supernova Legacy Survey (SNLS) uses high-redshift Type Ia Supernovae (SNe Ia) to constrain the nature of dark energy. The latest results from SNLS show that dark energy behaves like a pure Einstein cosmological constant. I will give a brief update on the current status of the survey, and discuss some recent results on the nature of Type Ia supernovae.
