Spectra and gradients Measuring spectral line-strengths
and their spatial variations across spheroidal systems (ellipticals,
lenticular, spiral bulges and cD galaxies). Abundance and age distributions
in stars mainly determine the spectral feature strengths in integrated stellar
populations. A major problem is dientangling the two effects of age
and abundance. This work is in collaboration with postgraduate students
and with external collaborators.
See GCE description page for details.

emission from the disc and bulge.
