Episode 6 of Season 1 sees us join Jack Line, a Research Associate at the Curtin Institute of Radio Astronomy in Western Australia to discuss the things that make radio astronomers go GaGa. Jack is part of a research group trying to detect the presence of the very first stars early in the life of the Universe. His main gig these days is trying to simulate what a telescope called the Murchison Widefield Array (MWA) sees, and comparing it to real data, to help astronomers understand what they are seeing. Join us as we have our finest hour and go Radio Gaga with Jack Line.
