Astro Seminar Series - VIA ZOOM

Ana Ennis is currently a PhD fellow from CONICET, Argentina, who will soon be joining the University of Waterloo as a postdoctoral fellow. Her main research interests are the formation and evolution of galaxies, and she has mainly worked on studying the evolutionary history of early-type galaxies using discrete tracers such as globular clusters and planetary nebulae.

Discrete tracers as tools to untangle the evolutionary history of early-type galaxies

Characterizing the stellar populations of early-type galaxies is a key tool for untangling their evolutionary histories, which has proven to be a crucial step towards understanding galaxy evolution as a whole. In nearby galaxies, the properties of stellar populations can be mapped through the study of individual red giant branch stars. At larger distances, resolving individual stars become too expensive, and discrete tracers come into play. In this talk, I will give an overview of some of the different ways in which globular clusters and planetary nebulae can be used for this purpose.
