Episode 11: A Trip Down Under
with Dr Ivy Wong, Dr Brenda Namumba and Professor Peter Quinn
Jacinta takes us on a tour of her homeland, into the Australian bush, and chats about pathfinders, precursors and the exciting collaborations between South Africa and Australia!
Precursor telescopes like the South African MeerKAT and HERA (Hydrogen Epoch of Reionisation Array), along with the Murchison Widefield Array (MWA) and Australian SKA Pathfinder (ASKAP) are providing SKA scientists with invaluable knowledge to assist in the design of the SKA’s main telescopes over the coming decade.
Pathfinder telescopes and systems, such as the now-retired KAT-7 (Karoo Array Telescope) are dotted around the globe and are also engaged in SKA related technology and science studies.
First, we hear from Dr Ivy Wong, a researcher at the International Centre for Radio Astronomy Research (ICRAR) in Perth, about large surveys of neutral hydrogen gas in galaxies and the results shared at the 12th PHISCC (Pathfinders HI Science Coordination Committee) Conference.
Neutral Hydrogen atoms produce radio emission at a wavelength of 21cm or a frequency of 1420 MHz. This emission is commonly referred to as HI and it is the raw fuel of star formation.
We are then joined by newly capped Dr Brenda Namumba from the University of Cape Town. She tells us about her exciting work using the pathfinder to MeerKAT, the KAT-7 telescope.
Finally, Jacinta sits down with Professor Peter Quinn, the Director of ICRAR. They chat about the the incredible growth of radio astronomy in both South Africa and Australia over the recent years, and the enormous collaboration opportunities the SKA is creating between the two countries!
