Description

We investigate the possibility that parametric resonant excitation of photons in an ultralight dark matter halo could generate the required flux of Lyman-Werner photons to allow the direct collapse formation of supermassive black hole seeds. This scenario provides a plausible explanation for the origin of quasars observed at high redshifts.
