I will describe Chandra observations of several clusters of galaxies and show that Chandra 's arcsecond angular resolution enables studies of the physical processes in the intracluster medium in an unprecedented detail . Distant clusters of galaxies provide unique insight into cosmology , the formation of large scale structure , and the formation and evolution of galaxies . Experiment with what works best for you . High redshift radio galaxies are fundamentally important probes of galaxy and cluster formation . Their uniquely wide fields of view mean that entire clusters of galaxies can be observed simultaneously . '' About six emails later , having explained to them that the book had not yet been released and one could not order it used I am still no further ahead . To address such questions as well as to find high-redshift clusters of galaxies , we applied optical and X-ray techniques to the areas of sky surveyed by deep ROSAT PSPC images . Nothing happens , because there is nothing to capture the information .
