Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

Episode 24 features Professor Kavilan Moodley who joins us to discuss another exciting project in radio astronomy in South Africa, HIRAX!

 

The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio telescope array that will map nearly all of the southern sky over a frequency range of 400 to 800 MHz. The primary goal of HIRAX is to measure baryon acoustic oscillations (BAOs): these are remnant ripples in the distribution of galaxies that originate from primordial sound waves that existed in the early universe.

 

This can be used for charting the expansion history of the universe and for shedding light on the nature of dark energy.
