Stellar Populations in Galaxies

Specialized course for Master students, listed on Moodle and heiCO

 

Course content (short summary): As most of the radiation we receive from galaxies is star light, we can use it to measure and study their properties. These lectures aim at showing how much we can learn about galaxy evolution from the study of their stellar populations (young to old stellar clusters, field stars, resolved and integrated stellar populations). We will review the methods commonly used in this respect, all resting on our understanding of stellar evolution, and discuss the results obtained when we apply them to observational data, such as multi-wavelength photometry and spectroscopy.
