This paper presents light curves and spectra of six Type Ia supernovae (SNe Ia) at high redshifts (0.511 < z < 1.12) and adds them to the Union compilation, resulting in the new Union2 compilation of 557 SNe. The study refines the analysis of these supernovae using the SALT2 fitter and improves the handling of systematic errors, confirming that the flat ΛCDM model fits the data well. The findings also provide updated constraints on the equation-of-state parameter w, indicating no significant change with red
