Unveiling the Evolution of Filamentary Structures Over the Past 8 Gyr Based on ΛCDM Cosmology 

 

Abstract: Cosmic filaments serve as fundamental structures shaping the large-scale universe. This presentation explores the evolution of filamentary structures over the past 8 Gyr based on the ΛCDM cosmological simulation. A key aspect of this study is GrAviPaSt, a method we designed for efficient filament identification. I will discuss key properties such as filament length, thickness, mass density contrast and radial profiles, alongside dynamic characteristics like galaxy distribution within filaments and velocity trends. Furthermore, I highlight distinct differences in filaments connecting galaxy groups versus those linking galaxy clusters, particularly in their mass density contrast profiles.
