Galaxies and Environment of the Clusters of Galaxies CL 0024+1654 and RX J0152.7-1357
We present the analysis and results of photometric and spectroscopic cata log combined with X-ray data of two non-relaxed clusters CL 0024+1654 (Ζ=0.4) and RX J0152.7-1357 (Ζ=0.8). Using the Spearman correlation analysis we quantify the correlation between morphology, color, and star formation rate of each galaxy with its surrounding number density, mass density, and temperature of Intracluster Medium (ICM). Although our results show that the two clusters exhibit a weaker correlation compared with relaxed clusters, it still confirms the significant effect of the ICM in varying the star formation rates in the galaxies. Various physical mechanisms have been suggested to explain the relation between the properties of galaxies and their en vironments for example: ram pressure stripping, mergers etc. Nonetheless, using this analysis alone, it is difficult to identify the dominant environmental mechanism(s) operating in clusters of galaxies and the role of the initial condition.
