Scientific paper

We use the Integrated Sachs-Wolfe (ISW) effect to probe the evolution of the gravitational potential from redshift 0.1-2. We cross-correlate the temperature fluctuations in the CMB measured by the WMAP satellite with three low redshift tracers of the matter distribution : the 2MASS galaxy sample (z=0.0-0.3), the SDSS Luminous Red Galaxies (z=0.2-0.6), and SDSS quasars (z=0.7-2.5). We present results from a combined analysis of these data, including constraints on cosmological parameters.
