Fermionic dark matter halos around supermassive black holes can form non-power-law spikes or even density depletions, depending on the fermion mass and degeneracy, instead of the universal r^-3/2 spike of power-law halos.
This is markedly different from the spike density profile from power-law DM density halos, which depends only on the initial power-law index γ

Fermionic Dark Matter spikes: origin and growth of Black Hole seeds
Fermionic dark matter halos around supermassive black holes can form non-power-law spikes or even density depletions, depending on the fermion mass and degeneracy, instead of the universal r^-3/2 spike of power-law halos.
