Dr Leah Morabito

I am an astronomer using radio telescopes to answer fundamental questions on how super-massive black holes co-evolve with the galaxies in which they reside.
My specialty is high-resolution imaging at low frequencies, using a Square Kilometre Array pathfinder telescope, the Low Frequency Array.
I am currently a Hintze Fellow and the Millard and Lee Alexander Postdoctoral Fellow at Christ Church, University of Oxford. Outside of work, I am an avid reader, I love to sew, and I row for Christ Church!

7 Nov 2019Black 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.
