A CANDIDATE FOR ZERO AGE CLUSTER A1913


ABSTRACT

The hierarchical clustering theory is one of the standard theory for galaxy and cluster formation. This theory predict presence of zero age cluster of galaxies. We selected A1913 as a candidate for zero age cluster. ASCA observation can discriminate zero age cluster by mass density of dark matter and mass ratio MFe/Mstellar.
