Explore scales beyond our comprehension in this evening exploring the wonders of the universe. We first explore the magnificent world of galaxy clusters, learning how these incredible structures change and evolve. We then explore Dark energy discovering what it is and how we can map it by looking at distant galaxies. Finally we dive down to the nanoscale, looking at how fluid behavior changes when we work on such a small scale - and ask what menace can occur when water is introduced!
Galactic Tides
Claire Cashmore
(Lecturer)
Galaxy clusters are hostile environments for galaxies; they can be ripped apart by galactic tides and have their gas stripped away through fluid interactions. Through these processes, galaxies are transformed from blue, star-forming spiral galaxies into 'red and dead' elliptical galaxies. Jellyfish galaxies form as a result of gas being stripped away from the galaxy, creating spectacular long tails of gas with the appearance of tentacles, which can host extragalactic star formation. In this talk, we will explore the evolution and fate of these galaxies as a result of their environment.
Exploring Dark Energy with Maps of Distant Galaxies
Daniel Farrow
(Lesturer)
About 96% of the Universe is thought to be made up of Dark Energy or Dark Matter, two things we do not understand and that might not even exist. Learn why astronomers think they exist, what we do know about them and what implications they have for the ultimate fate of the universe. You will also learn how astronomers at the University of Hull are helping make and analyse maps of distant galaxies to address these questions.
Flow Wars: The Nano Menace
Daniel Whitt
(PhD Student, University of Hull)
Why is it when we work with smaller and smaller cavities, and look at the nanoscale behavior of some liquids unusual things occur. Lets see what menace occurs when we put water in nanocavities.
