Galaxies in the universe trace patterns on very large scales; there are large empty regions (called “voids”) and dense regions where the galaxies exist. This distribution is called the cosmic web. The ...

The scaffolding that holds the large-scale structure of the universe constitutes galaxies, dark matter and gas (from which stars are forming), organized in complex networks known as the cosmic web.

Recent studies have suggested that vortices in ultralight dark matter halos could provide new insights into the formation of cosmic structures, challenging traditional models of galaxy evolution. A ...
