Description
We use high resolution three-dimensional simulations of reionization to develop a framework for interpreting
upcoming 21-cm observations. These simulations have a dynamic range in excess of 3,000 at all points in the
volume, on comoving (angular) scales from ~1 Mpc (arcminute) to several Gpc (tens of degrees). At these scales,
first generation 21-cm experiments are expected to be sufficiently sensitive to detect the fluctuating signal from
reionization. Because our simulations are highly-optimized using spectral filtering techniques, we can efficiently
survey parameter space to distinguish between different reionization histories, source populations, and IGM
absorption models. In order to maximize the constraints of the observations on theory, we present several new
diagnostics that should be applied to the first generation of large-scale 21-cm measurements.
