Dark matter dynamics in Galactic center

Understand

The evolution of dark matter in central areas of galaxies is considered (the Milky Way is taken as an example).

• It is driven by scattering off of dark matter particles by bulge stars, their absorption by the supermassive black hole and self-annihilation.
• This process is described by diffusion equation in the phase space of energy and angular momentum.
• The equation was integrated for several different models of initial dark matter distribution and using various assumptions about the dynamical factors.
