Jaan Einasto portrait

Work

Dark matter and the cosmic web define the mass distribution that controls galaxy formation on the largest scales.

Einasto contributed to evidence for massive dark halos and to mapping superclusters and filamentary cosmic structure.

His work helped shift cosmology toward a universe dominated by unseen matter organized in a web-like large-scale pattern.
