Description
Dark matter halos are complex evolving objects. In this talk I will discuss a study of the internal structures of dark matter halos using clustering algorithms in higher dimensional phase space, to see if they can pick up dynamical structures that are agnostic of pre-defined boundaries in the dark matter halos. We use the UMAP algorithm to visualize these distinct structures and find that the current halo structure encodes information about halo accretion history.
