Wednesday 05 Sep 2018[Seminar] The tidal disruption of disc galaxies

Alex Pettitt - Hokkaido University

Harrison H102 14:30-15:30

Disc galaxies come in a wide range of morphologies, with the most striking features being the long inner bars and winding spiral arms. While some galaxies appear to be effectively isolated systems, many reside in denser environments, experiencing interactions with their galactic neighbours which can directly impact their morphology. The resulting tidal forces in such interactions can drive clear changes in the gaseous and stellar components, such as altering bar dynamics, inducing bursts of star formation, and altering the properties of giant molecular clouds. In this talk I will discuss ongoing simulation work to better understand such interacting systems, and how they can aid in interpreting results of modern observational surveys of galaxies.
