The Murchison Widefield Array (MWA) is a joint project between MIT, the Harvard-Smithsonian Center for Astrophysics, the Raman Research Institute and an Australian consortium of universities, to build a low-frequency radio array operating in the frequency range 80-300 MHz. The main scientific goals of the MWA are to detect neutral atomic Hydrogen emission from the cosmological Epoch of Reionization, to study the sun/heliosphere/ionosphere, and to study radio transient phenomena. The MWA is the first so-called large-N array, fully cross correlating signals from 512 phased tiles of 16 crossed dipole (each). The field of view is large by the standard of astronomical instruments, being on the order of 30 degrees across.
