Metallicity gradient in the halos of external galaxies
Abstract
I will discuss recent measurements of metallicity gradients in the halos of massive galaxies using integrated light observations. I will compare observations from my group using integral-field spectroscopy, with those inferred from globular cluster studies and studies of color-magnitude diagrams for nearby galaxies. Then I will link these observations to inferences about the assembly history of massive galaxies.
