Extragalactic topics include large scale structure, galaxy structure, formation and evolution, stellar populations, and the ISM in galaxies. There are several primary research groups, with considerable overlap and cross-talk between them.

ISM in galaxies. In particular, there is considerable expertise on the warm interstellar medium, and interactions of stars with the ISM.

• Stellar populations in galaxies.

• Galactic structure.

• Quasar Absorption Line – Galaxy Evolution Group

• Distant galaxies, and field and cluster galaxy evolution.

• Galaxy formation.

• Large scale structure.
