"Observing the Epoch of Reionization with the MWA"

Highly redshifted 21 cm emission from the Epoch of Reionization (EOR) is a unique cosmological probe, and upcoming EOR radio observations could revolutionize our understanding of structure formation and the emergence of the first luminous objects. However, 21 cm EOR observations are complicated by strong foreground contamination and stringent instrumental requirements. In this talk, I will review the observational signatures of the Epoch of Reionization and how the faint 21 cm emission can be extracted from the foreground signals, and describe the Mileura Widefield Array (MWA) my colleagues and I are constructing in Western Australia. In addition I will discuss the promise of radio transient observations as a new cosmological probe.
