Stellar Populations and the Structural Evolution of Galaxies
Event Start:
2020-06-29T15:00:00
Event End:
2020-06-29T16:00:00
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.
