Episode 24 features Professor Kavilan Moodley who joins us to discuss another exciting project in radio astronomy in South Africa, HIRAX! HIRAX is a radio telescope array that will detect 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.
Prof Romeel Davé, from the Royal Observatory Edinburgh, and who spent 5 years working in Cape Town, introduces us to simulations! He explains how we can use simulations to perform experiments to test our understanding of the physics of the Universe.
