Abstract
We consider theories with global monopole or global texture defects and compute the number density of nonlinear seed fluctuations as a function of mass and redshift. Specifically, we focus on the mass range which is expected to be relevant for seeding supermassive black holes. We find that there is an interesting range of symmetry breaking scales for which the density of seeds is larger that what is predicted in the standard cosmological model with Gaussian primordial fluctuations. Hence, global defects may help in light of the mounting tension between the standard cosmological model and observations of supermassive black hole candidates at high redshifts.
