Abstract

The morphology content of galaxy clusters at intermediate redshifts differs significantly from those nearby ones (Dressler et al. 1997, ApJ, 490, 577). Studying clusters at higher redshifts and their connection to present day cluster properties is a subject of debate. Galaxy properties, as morphology, luminosity, mass, age, etc. and intracluster medium are expected to be strongly related to cluster assembly. Massive systems have been widely studied both in the nearby universe and at higher redshifts. Intermediate mass systems were not systematically nor deeply studied. We believe that intermediate mass clusters at intermediate redshifts are very important to understand the galaxy evolution in the herarquical model. Deep photometric and spectroscopic studies of these intermediate-mass systems at different redshifts would allow us to disentangle the different mechanisms involve in their evolution as ram pressure, galaxy interactions, etc. We propose to perform deep images using GMOS at GEMINI NORTH telescope of 8 intermediate-mass low X-ray galaxy clusters at redshifts between 0.3 < z < 0.7.
