The Murchison Widefield Array (MWA) is a radically new type of radio telescope, with no moving parts, and dependent on prodigious computer power to create exquisite real-time wide-field images of the radio sky.

The MWA is a low-frequency radio telescope, located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia where the future Square Kilometre Array (SKA) low-frequency array will be built. The MWA is a collaboration between 21 research institutions in six countries (Australia, Canada, China, Japan, New Zealand and the United States) and is led by Curtin University.

The MWA is designed to have a wide field of view on the sky thanks to the thousands of small, dual-polarization dipole antennas spread over several kilometers at the MRO site. These give the MWA flexible angular resolution and nanosecond time resolution – making it invaluable for quick sky mapping and the study of rare and faint events as they happen. MWA is also highly versatile and adaptable through signal processing.

Funding for MWA is provided by NCRIS via AAL. This funding provides support for staff salaries, infrastructure maintenance, utilities, and MRO rental costs. 

MWAX Correlator

The signal processing operations of the Murchison Widefield Array (MWA) telescope are mainly achieved by a correlator.  A new correlator, dubbed ‘MWAX’, has been designed with increased functionality to remove arbitrary limits and support more flexible observing modes and the expansion of the telescope.

Successful commissioning of the MWAX correlator will be a significant achievement for the MWA. This involves in-house software development, procuring and benchmarking state-of-the-art hardware systems, end-to-end testing, deployment, and installation on site, and finally technical and science commissioning. This is the crux of a highly anticipated upgrade which will enable a broader range of science cases and increase the quality and availability of MWA data.
