Event Information:

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 galaxy structural properties, but the physical reasons remain disputed.  I will discuss issues of correlation and causation, and highlight evidence from integral-field-unit surveys, hydrodynamical simulations and machine learning that point to multiple evolutionary pathways along which galaxies both grow and die.
