Episode 56: Our supermassive black hole
The Event Horizon Telescope (EHT) Collaboration has unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy! We are joined by Dr Iniyan Natarajan who is a postdoctoral fellow at the University of Witwatersrand and who was part of the team of over 300 astronomers who made this possible.
Episode 52: Head Space
In this week’s episode, we take a step back from astronomy and focus on mental health in academia and beyond. We are joined by Dr Jack Radcliffe, an astronomer from the University of Pretoria who speaks to us about his work on galaxy evolution, as well his recent efforts to speak out about mental health challenges facing academics in particular.
Episode 31: Cosmic Beasts and Where to Find Them
This year we get off with a bang as our very own Jacinta has a new paper out and takes her turn in the hot seat to tell us all about it! Along with her colleagues, she has been part of the discovery of two giant radio galaxies using South Africa's powerful MeerKAT telescope. These galaxies are amongst the largest single objects in the Universe and are thought to be quite rare. The fact that MeerKAT detected two of these monsters in a relatively small patch of the sky suggests that giant radio galaxies may actually be much more common than previously thought.
