High-redshift Mini-haloes from Modulated Preheating
Abstract
Intermittent type of primordial non-Gaussian fluctuations from modulated preheating can produce an overabundance of mini-haloes at high redshift . This may have a significant impact on the formation of high-redshift supermassive black holes.
