We continue our discussion from Episode 8 on simulating the Universe, this week focusing on the simulation of actual galaxies.
Nicole explains the SIMBA suite of simulations she is working on. SIMBA is a set of simulations which look at how the super-massive black holes at the centre of galaxies affect the galaxy they live in. She also talks about her experience growing up and studying in Cape Town, and some of the challenges she’s faced.
Nathan chats with us about his work creating individual galaxies within a computer using a new code he has just published. Using this we can learn more about how galaxies change over time and interact with their environments.

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.
