Función de Luminosidad de galaxias en cúmulos SDSS con ``redshifts (original) (raw)

Abstract

We use the photometric redshifts technique to estimate redshifts in clusters for galaxies and field in the Sloan Digital Sky Survey (SDSS) without spectroscopic determinations. We apply the method of background discont modified to determine luminosity functions of galaxies in clusters beyond the spectroscopic limit of the SDSS. Preliminary results show that the use of photometric redshift and a cluster
