Abstract: Supermassive black holes at very high redshift (z>6) are difficult to explain in standard astrophysical scenarios. We study the possibility that totally dissipative self-interacting dark matter is responsible for the existence of those black holes. A series of N-body simulations for dark matter halos and Monte Carlo simulations for halo merger trees are combined to compute the cosmological abundance of supermassive black holes in this scenario and the quasar luminosity function at high redshift is successfully reproduced. We will also show the signal of this scenario is very unique and future observations of quasars at high redshift could probe dark matter physics.
