Description
Distant clusters of galaxies provide a powerful method to study the formation and evolution of galaxies, and large scale structure of the Universe. However, the number of known clusters at high redshift (z > 0.5) is still very reduced. As a preparatory work for detailed studies with GTC, we are searching for high redshift clusters in public wide optical surveys. We will complement this with near IR observations in 4 m-class telescopes. Here, we present some preliminary results. In a field of 35×35 arcmin2 we have detected 8 clusters of galaxies at redshift z > 0.5.
