X-RAY OBSERVATION OF THE MOST DISTANT CLUSTER PDCS009
ABSTRACT
Since the X-ray emitting ICM comprise the major components of the visible matter of the clusters, to investigate evolution of X-ray properties of clusters is a key study of cosmology. Because there is a hint of evolution of clusters at the epoch of $z>0.6$, we propose ASCA observation of PDCS009, which is one of the most distant clusters at $z=1.20$.
