Felix

Felix is a topology based framework for exploring filament structures in the Cosmic Web [1]. The large scale filamentary network forms an intricate part of the cosmic web. The filamentary structure is represented in Felix by a subset of the Morse-Smale complex of the density field. We generate a hierarchy of Morse-Smale complexes and support queries for filaments based on the density ranges at the end points of the filaments. The query is processed efficiently over the entire hierarchical Morse-Smale complex allowing for interactive visualization.
