Dark matter haloes: a multistream view

Understand

Mysterious dark matter constitutes about 85% of all mass in the Universe.

• Clustering of dark matter plays the dominant role in the formation of all observed structures on scales from a fraction to a few hundreds of Mega-parsecs.
• Galaxies play a role of lights illuminating these structures so they can be observed.
• The observations in the last several decades have unveiled opulent geometry of these structures currently known as the cosmic web.
