HIRAX

(Hydrogen Intensity and Real-time Analysis Experiment)
(radio telescope array 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. Funding of the initial 256 dishes has been announced as of 2021.
