Galaxy evolution in clusters
In addition to studies of cluster star formation, aim to push back cluster studies to earlier epochs
- very deep optical / IR imaging around zɭ.5 RGs
- cross-correlation statistics
- colour-magnitude diagrams
- photometric redshifts
- follow-up multi-object spectroscopy (Gemini)
- evolution of cluster environments
- age-dating of evolved elliptical galaxies (Jimenez)
Just one massive cluster at this redshift has severe consequences for LSS and cosmological models.
