Modeling the core-halo mass relation in fuzzy dark matter halos

Understand

Fuzzy dark matter (FDM) is an intriguing candidate alternative to the standard cold dark matter (CDM).

• The FDM model predicts that dark halos have characteristic core structures generated by the effect of quantum pressure, which is different from the structure of CDM halos.
• We devise a semi-analytic model of a FDM halo density profile by assuming that the density distribution results from the redistribution of mass in a halo with the Navarro-Frenk-White profile.
• We calculate the mass redistribution radius by considering dynamical relaxation within the FDM halo.
