Density Perturbations in Hybrid Inflation Using a Free Field Theory Time-Delay Approach

Evangelos Sfakianaki
MIT

Abstract:

Using the Gaussian probability distribution of the mode amplitudes, we express the time-delay power spectrum as an integral which can be carried out numerically. A characteristic of the spectrum is the appearance of a spike at small length scales, which could conceivably seed the formation of black holes that can evolve to become the supermassive black holes found at the centers of galaxies.
