The Australian Radio Quiet Zone - Western Australia: Objectives, implementation and early measurements
MetadataShow full item record
The Australian Radio Quiet Zone - Western Australia (ARQZWA) has been established to protect new generation radio astronomy instruments, including the Australian component of the Square Kilometre Array (SKA). Using characteristics of typical transmitters and applying propagation prediction methods, various zones were established with appropriate protection measures. Legislation and regulatory policy has been implemented at Commonwealth and State level to protect the site from terrestrial radio transmissions and incidental emissions. Radio frequency interference detected by telescopes on the site has originated from distant sources, typically via anomalous propagation. The quietness of the site is already demonstrated in new astronomical discoveries.

(2015)We present results from the first 12 months of operation of Radio Galaxy Zoo, which upon completion will enable visual inspection of over 170 000 radio sources to determine the host galaxy of the radio emission and the ...
Mignano, A.; Prandoni, I.; Gregorini, L.; Parma, P.; De Ruiter, H.; Wieringa, M.; Vettolani, G.; Ekers, Ronald (2008)Context. One of the most debated issues about sub-mJy radio sources, which are responsible for the steepening of the 1.4 GHz source counts, is the origin of their radio emission. Particularly interesting, from, this point ...
