Next Meeting: Wednesday May 12 at 8:00pm on Zoom How to build a Universe Chris Lovell
Galaxies are as diverse and complex as people, however, they also evolve over distinctly non- human time scales and their unfathomable size means they can’t be poked and prodded in a laboratory. Instead, to unlock the secrets of their formation and evolution, we look out into the Universe using telescopes (such as the Hubble Space Telescope or upcoming Webb Space Telescope). Unfortunately, these only provide a snapshot of a galaxy, frozen in time. To truly understand how galaxies evolve we need something else: simulations! But how do these work? How do you take a computer and reproduce a population of galaxies? In this talk, Chris will show exactly how astrophysicists build these toy Universes, and how they help us understand our own Universe’s past, present and future. Chris Lovell graduated from Cardiff University with a Masters in Astrophysics. He then spent a couple of years working at the Bank of England before coming back to Astronomy, doing his PhD at the University of Sussex. He is now a postdoctoral researcher at the University of Hertfordshire.
