Episode 4: Black holes and Radio Jets

with Dr Imogen Whittam and Lerato Sebokolodi

Episode 4 features Dr Imogen Whittam, a SARAO Postdoctoral Fellow at the University of the Western Cape and Lerato Sebokolodi a PhD student, based at SARAO and the National Radio Astronomy Observatory (NRAO) in the USA.

Imogen talks about her work on Active Galactic Nuclei (AGN), stemming from the super-massive black holes that reside at the centre of most galaxies and how we learn how these massive beasts work.

Lerato chats about one AGN in particular, the famous Cygnus A and her work on the magnetic fields that drive the formation of the beautiful jets pictured below.
