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 Lines
- Distant galaxies, and field and cluster galaxy evolution.
- Galaxy formation.
- Large scale structure.
Members of the Extragalactic Group include the following:
