The left image shows the hydrogen gas density of a simulated dwarf galaxy, viewed from above. The right image shows the same for a real dwarf galaxy, IC 1613. In the simulation, repeated gas inflow and outflow causes the gravitational field strength at the center of the dwarf to fluctuate. The dark matter responds to this by migrating out from the center of the galaxy, an effect known as ‘dark matter heating’.
