Title: Simulating Reionization: Character and Observability Author(s): Ilian Iliev, Paul Shapiro, et al. Abstract: We have recently performed the first large-scale radiative transfer simulations of reionization. These are run on top of the largest and most detailed simulations of early structure formation to date which resolved halos down to dwarf galaxy scale in very large volumes, up to 100/h Mpc. We showed that the reionization process is strongly self-regulated and that it has a fairly large characteristic scales, at wavenumbers of k~1 h/Mpc, which is similar to the typical resolution of planned experiments, at arcminute scales. This allowed us for the first time to make realistic observational predictions of the Epoch of Reionization observables based on detailed radiative transfer and structure formation simulations. I would present our predictions for the progress and features of reionization under different scenarios and would discuss in detail the observability of this epoch with current and upcoming experiments at redshifted 21-cm line of hydrogen (with e.g. LOFAR, GMRT, MWA and SKA), for measuring the small-scale CMB temperature anisotropies from kinetic Sunyaev-Zeldovich effect and CMB polarization anisotropies (with e.g. ACT and SPT) and for observing high-redshift Ly-alpha sources in both emission and absorption.
