Clusters and Environment
Automated cluster selection from 2dFGRS will give a cleanly-selected, unbiased 3D cluster catalogue of ~250 rich Abell clusters plus many poorer groups and clusters with all members down to bJ=19.45.
Cluster catalogue and 3D density maps ? tests of effects of local density (i.e. ‘environment’) on galaxy properties and evolution.
For now, however, the highly variable completeness over the survey volume limits our ability to find clusters and estimate the local density.
