A study of the dynamical structures in a Dark Matter Halo using UMAP
Soorya Narayan R., Susmita Adhikari
We use a dimension reduction algorithm, Uniform Manifold Approximation and Projection (UMAP), to study dynamical structures inside a dark matter halo. We use a zoom-in simulation o…

Dynamics-based halo model for large scale structure
Edgar M. Salazar, Eduardo Rozo, Rafael García +4
Accurate modelling of the one-to-two halo transition has long been difficult to achieve. We demonstrate that physically motivated halo definitions that respect the bimodal phase-sp…
