The Clustering of Colour Selected Galaxies

Measurements of the clustering of galaxies selected from a $B_J\sim 23.5$
multicolour survey of two $5^\circ \times 5^\circ$ fields are presented.
Measurements of the $z\sim 0.4$ correlation function at large angular
scales show no evidence for a break from a power law though these results
are not inconsistent with a break at $\ga 15 h^{-1} {\rmn Mpc}$. Colour
selection is used to study the clustering of galaxies $z\sim 0$ to $z\sim
0.4$. The galaxy correlation function is found to strongly depend on
colour with red galaxies more strongly clustered than blue galaxies by a
factor of $\ga 5$ at small scales. The strong dependence of clustering
properties on colour suggests galaxy clustering is more strongly
correlated with colour (stellar population) than morphology.
