We cross-correlate the third-year WMAP data with galaxy samples extracted from the SDSS DR5 (SDSS5) covering 16% of the sky. These measurements confirm a positive cross-correlation, which is well fitted by the integrated Sachs-Wolfe (ISW) effect for flat LCDM models with a cosmological constant. The combined analysis of different samples gives Ω_Λ=0.79-0.83 (68% Confidence Level, CL) and Ω_Λ=0.75-0.85 (95% CL).
