Self-similar Decomposition of the Hierarchical Merger Tree of Dark Matter Halos

In the ΛCDM universe, structure formation is generally not a self-similar process, while some self-similarity remains in certain statistics, which can greatly simplify our description and understanding of the cosmic structures. In this work, we show that the merger tree of dark matter halos is appro...
