Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS                      
  Title: DISTANT CLUSTERS OF GALAXIES WITH GIANT LUMINOUS ARCS                           


Abstract:
 We propose to observe the distant lensing clusters of galaxies with great luminous
 arcs, which are extensively observed in optical and radio in order to determine the
 detailed dynamics and the properties of cluster members. Using the configurations of
 arcs in optical, we can determine the total mass and mass distribution of clusters
 of galaxies. In X-ray wavelength, the electron temperature of intra-cluster gas can
 allow us to determine them. In combine with the optical observations, it is possible
 to investigate the distribution of luminous dark matter. In the case of the distant
 clusters, we can also investigate the evolution of the clusters and the evolution of
 beta and core radius of clusters of galaxies.
