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 6: Galactic Neighbourhoods

with Prof Eric Wilcots and Sinenhlanhla Precious Sikhosana

In this episode, we speak with Prof Eric Wilcots and Sinenhlanhla Precious Sikhosana about galaxies and the environments they live in.

We discuss how and where galaxies form, and how they interact with other galaxies, and what effect that has on how these galaxies continue to evolve.

We also chat about how astronomers observe clusters of galaxies and the exciting science that will be coming out of the MeerKAT Telescope.
