The Supernova Legacy Survey

Astrophysics 2019-08-14 v1

Abstract

Type Ia supernovae (SNe Ia) currently provide the most direct evidence for an accelerating Universe and for the existence of an unknown "dark energy" driving this expansion. The 5-year Supernova Legacy Survey (SNLS; http://cfht.hawaii.edu/SNLS/) will deliver ~1000 SN Ia detections with well-sampled g'r'i'z' light curves. Using this definitive dataset, we will obtain a precise measurement of the cosmological parameters (Omega_m, Omega_lambda); our goal is to determine the cosmological equation of state parameter "w" to a statistical precision of +/-0.07, testing theories for the origin of the universal acceleration. In this proceeding, we summarise the progress made during the first full year of the survey operation.
