摘要：We present the recent cosmology results from the Supernova Legacy Survey (SNLS) 3 years analysis. Using 242 high redshift type Ia supernovae discovered and measured during the first 3 years of the Supernova Legacy Survey, together with other mostly nearby supernovae samples, we measure a dark energy equation of state parameter w consistent with a cosmological constant. The sytematic uncertainties are approximately equal to the statistical uncertainties. Combining the supernovae data with cosmological microwave background (WMAP7) and baryonic acoustic oscillations (SDSS) measurements, we obtain a measurement of the dark energy equation of state w = 1:068 with a precision of 0:08.
