Einasto's model has been used to describe many types of system, including galaxies and dark matter halos.

Dark matter halos play a key role in current models of galaxy formation and evolution.

Simulated dark matter haloes, like elliptical galaxies, never have elongations greater than about 3:1.

The research is the first time scientists have measured the three-dimensional shape of a dark matter halo .

To have survived this previous encounter, it is thought to be embedded inside a massive dark matter halo.

The dark matter halo is estimated to have 10 times the mass of the stars in the galaxy.

More recent theories include the clustering of dark matter halos in the bottom-up process.

It has also been suggested that the dark matter halo can pull the galaxy, thus stopping disk contraction.

This suggests that the galaxy is surrounded by a dark matter halo, which provides the necessary mass.

He is famous for his theoretical studies of dark matter halos accompanied by massive N-body simulations.
