Formation of MACHO-primordial black holes in inflationary cosmology.
Abstract
As a nonbaryonic explanation of massive compact halo objects, a phenomenological model is presented which predicts formation of primordial black holes at a desired mass scale. The required feature of initial density fluctuation is realized making use of primordially isocurvature fluctuations generated in an inflationary universe model with multiple scalar fields.
