Episode 31: Cosmic Beasts and Where to Find Them

1/18/2021
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...
