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.
In this mini episode, we chat to Andrew “Andy” Firth, a Masters students at the South African Astronomical Observatory and the University of Cape Town. Andrew tries to detect the faint signals of hydrogen gas in distant galaxies. He is creating an algorithm for stacking data cubes of these galaxies. This clever new technique will be used alongside high-quality MeerKAT radio telescope data.

Today we chat with Sambatriniaina Rajohnson about her work on the Galactic Plane Survey and the Zone of Avoidance. Check out the full show notes at www.thecosmicsavannah for more info, pictures, related links and the full transcript.
