We present initial results from the Jubilee ISW project, which models theexpected \LambdaCDM Integrated Sachs-Wolfe (ISW) effect in the Jubileesimulation. The simulation volume is (6 Gpc/h)^3, allowing power on verylarge-scales to be incorporated into the calculation. Haloes are resolved downto a mass of 1.5x10^12 M_sun/h, which allows us to derive a catalogue of mockLuminous Red Galaxies (LRGs) for cross-correlation analysis with the ISWsignal. We find the ISW effect observed on a projected sky to grow stronger atlate times with the evolution of the ISW power spectrum matching expectationsfrom linear theory. Maps of the gravitational lensing effect, including theconvergence and deflection fields, are calculated using the same potential asfor the ISW. We calculate the redshift dependence of the ISW-LRGcross-correlation signal for a full sky survey with no noise considerations.For l < 30, the signal is strongest for lower redshift bins (z ~ 0.2 to 0.5),whereas for l > 30 the signal is best observed with surveys covering z ~0.6-1.0.
