THE HIGH RESOLUTION MULTI-WAVELENGTH SURVEY PROGRAM OF THE DISTANT MASSIVE ROSAT ALL-SKY-SURVEY CLUSTERS II


ABSTRACT

Clusters of galaxies are key objects for understanding the origin and growth of structure in the universe. Measurement of temperature of ICM with ASCA are ideal for studying the potential wells, and thus the dynamical state, of these massive systems. We have selected 8 objects from the ROSAT All Sky Survey and undertaken to obtain a complete set of high resolution follow-up observations including studies of X-ray morphology, optical spectroscopy/photometry, and radio and IR measurements of cluster galaxies. In AO-4, we observed 5 out of the 8 clusters. In this AO, we will observe the rest 3 clsuters. All observations except for ASCA have already finished. The porject will be complete by the observations of ASCA.
