The Mileura Widefield Array is a low-frequency radio array planned for construction in the outback of Western Australia. In the next 3 years, we plan to build a demonstration array operating in the 80-300 MHz range, comprising 500 antenna systems, and capable of a variety of frontier scientific investigations. The instrument will feature a number of innovations that exploit modern digital signal processing capabilities, and implement functionality that has not hitherto been possible.
Among the science goals of the demonstration array is the first detection and characterization of the redshifted 21cm signal from neutral hydrogen during the period of reheating and reionization at redshifts from 6 to 16. The array will also enable a search for transient radio phenomena with a sensitivity that is 6 orders of magnitude better than current limits. The measurement of scintillation and Faraday rotation due to plasma in the heliosphere will be used to diagnose density and magnetic field parameters of coronal mass ejections, with application to space weather studies.
The project is a collaboration between MIT, CfA, the Australia Telescope National Facility, and multiple Australian universities.
