The cosmic web as a research area focuses on the large-scale matter distribution in the Universe, characterized by a network of filaments, walls, nodes, and voids formed by gravitational amplification of primordial density fluctuations in dark matter and baryons. This field integrates cosmological simulations, large galaxy redshift surveys, weak gravitational lensing, and Lyα forest tomography to quantify the web’s topology, connectivity, and anisotropic collapse. Key objectives include constraining cosmological parameters, dark matter and dark energy models, galaxy formation and environmental effects, and testing structure-formation theories within the ΛCDM framework or its alternatives through statistical analysis of web morphology and dynamics.
Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark ...
