Resumen o descripción
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.
