Mileura Wide Field Array and the Stromlo Streamer

Read here about the First Radio Light of the Mileura Wide Field Array Low Frequency Demonstrator, a collaborative project of Massachusetts Institute of Technology, Harvard University and several Australian Universities, including the ANU, Curtin University, and the University of Melbourne, and the ATNF.

	Mileura Station is located north of Perth, east of Geraldton in the state of Western Australia (left). Its low population density reduces the amount of human radio interference.	The assembly and testing of the first tile at Mileura station took a little over two weeks.
The dipole antennas, built at MIT, sit atop a groundscreen constructed at the University of Melbourne.	The prototype can collect useful data night and day.	From the air, it is clear that there is plenty of room to expand the demonstrator to add many more elements, or tiles. (Photo courtesy of P. Walsh)
The signals are sent to the backend system, which analyzes them. The digital backend (detector and spectrometer) was designed and built at Mount Stromlo Observatory.	The first spectrum was taken by the commissioning group on 11 March 2005.	The rising and setting of the Milky Way is clearly seen at several of the frequencies at which the system operates.
