Research questionHow can cosmic-web classifications unify large- and small-scale structure for halo-bias modeling?Cosmic-web definitions probe different spatial scales, making it difficult to relate environmental labels consistently to the scale-dependent information carried by halos and other tracers. This complicates their use in bias and clustering models.

Latest papersRecent research connected to this question, newest first.Spectral Hierarchy of the Cosmic WebThe source studies eigenvalue-based classifications of a filtered density field, including potential/tidal, curvature, and higher-derivative web levels. It measures web-contrast cross-correlations with halos from the AbacusSummit simulations on a coarse mesh with ΔL ≃ 5.5 h⁻¹ Mpc, supporting conclusions about tracer-relevant information across the represented scales.research paper · Sep 3, 2026
