Scientific paper

We present new u'g'r'i'z' photometry of the globular cluster Omega Centauri. We construct color-magnitude diagrams (CMDs) and color-color diagrams (CCDs) and fit these using the Girardi et al. 2004 isochrones to constrain the spread in the age and metallicity of the red giant branch. Finally, we briefly discuss the star formation history of this fascinating cluster.
