Caustic Skeleton and the Local Cosmic Web: the Coma Cluster node and the Pisces-Perseus ridge
Amelie Read, Job Feldbrugge, Celine Boehm +2
We apply caustic skeleton theory to the Manticore-Local simulations, which are Bayesian constrained reconstructions of the Local Universe from the 2M++ galaxy catalogue, and extrac…
Galaxy Populations in the IllustrisTNG Caustic Skeleton
Benjamin Hertzsch, Job Feldbrugge, Rien van de Weygaert
The caustic skeleton is a parameter-free and mathematically rigorous formalism for tracing the hierarchical formation history of the multiscale cosmic web from the singularities in…
Resurgence and Hyperasymptotics in Wave Optics Astronomy
Job Feldbrugge, Samuel Crew, Ue-Li Pen
With the discovery of gravitational waves and fast radio bursts, wave optics has become increasingly relevant in astrophysics. This paper studies the behaviour of random gravitatio…
A New Recipe for Caustic Pancakes: On the Reality of Walls in the Cosmic Web
Benjamin Hertzsch, Job Feldbrugge, Maé Rodriguez +1
The caustic skeleton model is a mathematically rigorous framework for studying the formation history of the emerging cosmic web from the caustics in the underlying dark matter flow…
What makes a cosmic filament? The dynamical origin and identity of filaments I. fundamentals in 2D
Job Feldbrugge, Rien van de Weygaert
Cosmic filaments are the main transport channels of matter in the Megaparsec universe, and represent the most prominent structural feature in the matter and galaxy distribution. He…
Phase-Space Delaunay Tessellation Field Estimator
Job Feldbrugge
The reconstruction of density and velocity fields is of central importance to the interpretation of -body simulations. We propose a phase-space extension of the Delaunay tessell…
