| Abstract: | In this paper, we present a “peak number count method”, based on wavelet transformation, and use it to explore the structure and substructures in the Virgo area. It is found that, besides the two-humped structure, there are also quite a lot of small subclusters with characteristic scales of 180′ and 120′. This result strongly supports the hierarchical clustering model of structures. The wavelet coefficient map clearly shows these substructures and their distributions. Additionally, two new small subclusters are discovered. |
