Galaxy and Mass Assembly (GAMA): Projected Galaxy Clustering
  We measure the projected 2-point correlation function of galaxies in the 180
deg$^2$ equatorial regions of the GAMA II survey, for four different redshift
slices between z = 0.0 and z=0.5. To do this we further develop the Cole (2011)
method of producing suitable random catalogues for the calculation of
correlation functions. We find that more r-band luminous, more massive and
redder galaxies are more clustered. We also find that red galaxies have
stronger clustering on scales less than ~3 $h^{-1}$ Mpc. We compare to two
different versions of the GALFORM galaxy formation model, Lacey et al (in
prep.) and Gonzalez-Perez et al. (2014), and find that the models reproduce the
trend of stronger clustering for more massive galaxies. However, the models
under predict the clustering of blue galaxies, can incorrectly predict the
correlation function on small scales and under predict the clustering in our
sample of galaxies with ~3$L_r$ . We suggest possible avenues to explore to
improve these cluster- ing predictions. The measurements presented in this
paper can be used to test other galaxy formation models, and we make the
measurements available online to facilitate this.
