Structure formation in cosmology proceeds in a hierarchical fashion, where dark matter halos grow via mergers with other halos. This type of evolution can be conceptualized as a tree, with small branches connecting to successively larger ones, and finally to the trunk. A merger tree describes the growth of halos in a cosmological simulation by linking a halo appearing in a given snapshot to its direct ancestors in a previous snapshot and its descendent in the next snapshot. Merger trees are computationally expensive to generate and a great number of codes exist for computing them. However, each of these codes saves the resulting data to a different format. ytree is Python package for reading and working with merger tree data from multiple formats.
