The importance of wide-field foreground removal for 21 cm cosmology: a demonstration with early MWA epoch of reionization observations

In this paper we present observations, simulations, and analysis demonstrating the direct connection between the location of foreground emission on the sky and its location in cosmological power spectra from interferometric redshifted 21 cm experiments. We begin with a heuristic formalism for unders...
