HIRAX
(Hydrogen Intensity and Real-time Analysis Experiment)
(radio telescope array for 21-cm surveying)
HIRAX (for Hydrogen Intensity and Real-time Analysis Experiment)
is a radio telescope array under construction in South Africa
to survey the redshifted 21-cm line from distant
galaxy clusters, to map large scale structure and to detect baryon acoustic oscillations. It
is to consist of 1024 6-meter dishes, receiving 400 MHz to 800 MHz.
It is similar to the Canadian Hydrogen Intensity Mapping Experiment (CHIME), but offers independent data with
different systematics. Ten prototype dishes have been
in service and funding of the initial 256 dishes has been announced
as of 2021.
