We characterize a sample of 91 Rich Abell Clusters using photometric and spectra measurements from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7). We determine cluster memberships, cluster velocity dispersions, cluster scales, surface brightness, total masses, luminosities and cluster luminosity functions. Also, we deal with theoretical concepts to estimate the cluster galaxies peculiar velocities and determine the cluster caustic curves, cluster core radius, virial radius and turn-around radius for all our cluster sample. In addition, we identify the most massive galaxy clusters in the Galaxy and Mass Assembly (GAMA) Survey. We develop a cluster finding technique that looks for 3D galaxy numerical overdensities. We use the Delaunay Tessellation Field Estimator (DTFE), followed by a caustic analysis to determine cluster masses.
