Description
We investigate the formation and relaxation of dark matter halos in the framework of wave dark matter particles evolving on a neutrino-condensate background. We numerically solve the Schrödinger–Poisson system to model the dynamical evolution of ultralight bosonic dark matter in the presence of a neutrino condensate. The latter is included as an additional source term in the Poisson equation, while its own dynamical evolution and interactions with the environment are neglected. We find that, depending on the value of the cutoff parameter, the neutrino-condensate background can affect both the formation and relaxation of wave dark matter halos. Nevertheless, for cutoff values of the order of a few eV, the two components can coexist with only marginal deviations from the wave dark-matter only case. These results open the way to the investigation of more complex cosmological scenarios involving the formation and evolution of dark matter halos in the presence of additional background components.
