The Jubilee ISW project – I. Simulated ISW and weak lensing maps and initial power spectra results

Abstract: We present initial results from the Jubilee Integrated Sachs-Wolfe (ISW) project, which models the expected ? cold dark matter ISW effect in the Jubilee simulation. The simulation volume is (6?h-1?Gpc)3, allowing power on very large scales to be incorporated into the calculation. Haloes are resolved down to a mass of 1.5 × 1012?h-1?M?, which allows us to derive a catalogue of mock Luminous Red Galaxies (LRGs) for cross-correlation analysis with the ISW signal. We find the ISW effect observed on a projected sky to grow stronger at late times with the evolution of the ISW power spectrum matching expectations from linear theory. Maps of the gravitational-lensing effect are calculated using the same potential as for the ISW. We calculate the redshift dependence of the ISW–LRG cross-correlation signal for a full-sky survey with no noise considerations. For l < 30, the signal is strongest for lower redshift bins (z ~ 0.2–0.5), whereas for l > 30, the signal is best observed with surveys covering z ~ 0.6–1.0.
