We present an analysis of the cluster properties and investigate the galaxy population in four X-ray low luminosity poor galaxy clusters at intermediate redshifts (two at and two at). The clusters were selected from the 160 Square Degree ROSAT Cluster Survey (Vikhlinin et al. 1998, ApJ, 502, 558). The analysis is based on deep imaging and spectroscopic observations obtained at Gemini telescopes (North and South) with the Gemini Multiobject Spectrograph (GMOS).
We have started a program to obtain images and spectra of galaxies in an X-ray selected sample of poor clusters in the redshift range of. Four poor clusters with X-ray luminosity were observed with the Gemini Multiobject spectrograph at Gemini South and North during 2003. The data were used to construct a catalogue of member galaxies in order to analyze the cluster properties and investigate the galaxy population.
In this work we present our results obtained for cluster [VMF98] 97, [VMF98] 102, [VMF98] 124 and [VMF98] 22 at redshift, and respectively. We analyze the cluster dynamics, galaxy distribution, color-magnitude relation and the galaxy morphology in order to determine the global properties of the clusters.
