What kills galaxies? | My Astrophysics PhD Thesis Part 1

By popular demand - a video all about my PhD research into what causes galaxies to stop forming stars (or "die"). From their shape, to supermassive black holes, to their environment, this thesis covered quite a bit of ground - so much that I waffled on for far too long. Part 2 coming soon!

Also HILARIOUSLY there’s a mistake in a video about my own thesis 😂 😭 [noticed after posting]. I’m blaming this one on the lockdown folks. I mislabelled the u- and r-band magnitudes. “U” is the blue band and “r” is the red band. What I said in the video about u-r being greater or less than 0 though still holds - this is because in astronomy the lower the magnitude number, the brighter something is. And the higher the number the fainter something is. A relic of a by-gone era. You all have my sincerest apologies from my mushy lockdown brain.
