Substructure of fuzzy dark matter haloes

18 Dec 2016 Du Xiaolong Behrens Christoph Niemeyer Jens C.

We derive the halo mass function (HMF) for fuzzy dark matter (FDM) by solving the excursion set problem explicitly with a mass-dependent barrier function, which has not been done before. We find that compared to the naive approach of the Sheth--Tormen HMF for FDM, our approach has a higher cut off mass and the cut off mass changes less strongly with redshifts... (read more)
