Episode 9: Simulating the Universe – Part 2
with Nicole Thomas and Dr Nathan Deg
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.
