The Jubilee ISW Project (simulated ISW) and using it to study voids

Abstract: What are the properties of dark energy? To answer this question, the late-time integrated Sachs-Wolfe (ISW) effect (Sachs & Wolfe 1967; Rees & Sciama1968; Hu & Sugiyama 1994) can be a useful cosmological probe, since it is sensitive to the dynamical effects of dark energy and may thus be used to discriminate between different cosmological models (Crittenden & Turok 1996; Afshordi et al. 2004). The Jubilee project consists of two of the largest N-body simulations done up to date. Two volumes of 3072 Mpc and 6000 Mpc respectively with same mass and spatial resolution. These simulations were intended to be used primarily to compute an all-sky map of the Integrated Sachs-Wolfe effect (or ISW) but also to produce catalogs of luminous red galaxies (or LRG), radio and IR galaxies as well as all sky maps of the Sunyaev-Zel’dovich (or SZ) and lensing effects.
