The population of galaxies in the distant clusters Cl 1613+3104 and Cl 1600+4109
Rosendo Vilchez-Gomez, Roser Pello, Blai Sanahuja
We study the photometric properties and content of the distant clusters of galaxies Cl 1613+3104 (z = 0.415) and Cl 1600+4109 (z = 0.540). The former is a rich, concentrated cluste…
