Dark-matter spike at the galactic center?
The past growth of the central black hole (BH) might have enhanced the density of cold dark matter halo particles at the galactic center. We compute this effect in realistic growth models of the present $(2\ensuremath{-}3)\ifmmode\times\else\texttimes\fi{}{10}^{6}{M}_{\ensuremath{\bigodot}}$ BH from a low-mass seed BH, with special attention to dynamical modeling in a …
