Title:     The Life and Death of Galaxies

Abstract: Livestream link: https://mediasite.audiovisual.ubc.ca/Mediasite/Play/3991ac4488234bf99557b0adfda185441d

It is well established that galaxies are divided into those that are star-forming and those that have stopped forming stars long ago.  The cessation of star formation in galaxies ("quenching") correlates strongly with both galaxy morphology and environment, but the physical reasons behind these relationships remain disputed.   Drawing upon my own research, I will discuss issues of correlation and causation, and highlight evidence that points to multiple evolutionary pathways along which galaxies both grow and die.
