Episode 8: Simulating the Universe

with Prof Romeel Davé 

Prof Romeel Davé, from the Royal Observatory Edinburgh, and who spent 5 years working in Cape Town, introduces us to simulations! He explains how we can use simulations to perform experiments to test our understanding of the physics of the Universe.

Romeel also talks about his time here in South Africa, and his involvement in the MeerKAT radio telescope and the general development of astronomy on the African continent.

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.

Episode 2: Instruments and Singing Asteroids

with Dr Amanda Sickafoose and Vanessa Lorenzo

In Episode 2, we hear from Dr Amanda Sickafoose who tells us about the complicated instrumentation her team are building for South African telescopes and some of her fascinating work on our Solar System.

Vanessa Lorenzo also talks to us about her time as artist-in-residence at the SAAO and her installation giving a voice to rocks and asteroids.
