Antennas of CSIRO's Australia Telescope Compact Array
The Australia Telescope Compact Array has been equipped with sensitive receivers enabling it to detect radio waves as short as 3.5 millimetres. The new receivers incorporate special CSIRO-designed chips, made of the high-performance material indium phosphide.
The new systems mean that the Compact Array will be the only set of telescopes in the southern hemisphere operating at these short wavelengths until the Atacama Large Millimetre Array telescope in Chile becomes operational at the end of this decade.
