November Meeting - Dr Leah Morabito

Our next monthly meeting is on Thursday, 7th November 2019 at 7:30pm.

Black holes that feed on galaxies

At the heart of almost every massive galaxy, there is a super-massive black hole. We see evidence in astronomical observations that these super-massive black holes are linked to the global properties of the galaxies in which they reside.
One of the biggest open questions in astronomy today is: how do super-massive black holes impact galaxy evolution?
A small fraction of super-massive black holes are in an 'active' phase, where they are feeding on gas from their host galaxies.
We can identify these active galaxies in astronomical observations, and study how they can help direct the path of galaxy evolution.
We do not yet know exactly how this happens, but in this talk you will learn about the phenomena powered by active super-massive black holes, with a focus on what can be learned from radio observations from telescopes like the Low Frequency Array.
I will cover both current indirect evidence for the co-evolution of super-massive black holes and their host galaxies, and upcoming work which will help definitively push forward our understanding of how super-massive black holes impact galaxy evolution.
