"Exploring the formation of massive early-type galaxies" , by Ignacio Ferreras (UCL/MSSL)
Extracting the formation history of galaxies from the properties of their (unresolved) stellar populations poses a major challenge. This problem is even harder in early-type galaxies, whose light is dominated by old, passively evolving stars. I will give a general overview of the field and present a novel approach to the extraction of star formation histories by the use of multivariate techniques such as Principal Component Analysis. |
