HIRAX (The Hydrogen Intensity and Real-time Analysis eXperiment)

Enlarged view: HIRAX Project Logo

The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array project under construction in South Africa. The project is an international collaboration with 24 partner institutions and is an official guest instrument on the Square Kilometre Array (SKA) South Africa site. The completed experiment will consist of a compact array of 1024 radio telescopes with each dish measuring six metres in diameter. These dishes are instrumented with dual polarisation feeds operating between 400 and 800 MHz. With its planned 4-year survey, HIRAX will achieve its science goals by mapping neutral hydrogen emission over a 15,000 square degree area of the southern sky between redshifts 0.8 and 2.5. This survey will enable the study of the evolution of dark energy through hydrogen intensity mapping, provide a sensitive probe of transient radio sources including fast radio bursts and pulsars, and yield a number of additional cosmological probes through cross-correlation studies with other cosmological surveys in the southern sky.
