The Murchison Widefield Array: A Low-Frequency Radio Telescope in Western Australia

How does one analyze PetaBytes of data to reveal the vanishingly faint cosmological signal from the Epoch of Reionization? The science return from EoR observations will be groundbreaking, but it is one of the most difficult and precise astrophysical measurements ever attempted. I will introduce the Murchison Widefield Array and some of our recent results, with a particular emphasis on the human endeavor of processing very large amounts of data at unprecedented levels of precision.
