Cosmic web, Large-scale structure, Observational cosmology.Abstract
Comprising dense nodes, filamentary structures, and cosmic voids, the cosmic web reflects fundamental large-scale matter distribution. A comprehensive exploration into the cosmic web will shed light on the processes governing the universe’s large-scale structural formation and evolution, validate cosmological models, enhance comprehension of galaxy formation and evolution, and provide deeper insights into dark matter and dark energy. This paper aims to investigate the cosmic web through observational cosmology, concentrating on methodological techniques, the defining traits of cosmic-web structures, their statistical attributes, evolutionary dynamics, and insights gained from observational analyses. However, relatively low observational precision and resolution and the gap between simulations and observational data are still severe problems for scientists. There will be more observational projects in the future, with the aim to integrate multi-wavelength and multi-method approaches and build a unified model describing cosmic-web structures and their evolutionary processes.
