- W2249656721 abstract "We consider the steady-state regime describing the density profile of a dark matter halo, if dark matter is treated as a Bose-Einstein condensate. We show that the problem of a negative density of the halo, arising when treating dark matter as a perfect fluid, is solved when an additional quantum term is included in the numerical computation of the density profile. The improved solution clumps dark matter closer to the galactic center. In addition, we derive and numerically solve the differential equation describing perturbations in the density and the pressure of the dark matter fluid, showing that density perturbations tend to clump near the boundary of the halo, with a broadening depending on the mass of the dark matter particle." @default.
