- Title
STRING GAS COSMOLOGY AND STRUCTURE FORMATION.
- Authors
BRANDENBERGER, ROBERT H.; NAYERI, ALI; PATIL, SUBODH P.; VAFA, CUMRUN
- Abstract
It has recently been shown that a Hagedorn phase of string gas cosmology may provide a causal mechanism for generating a nearly scale-invariant spectrum of scalar metric fluctuations, without the need for an intervening period of de Sitter expansion. A distinctive signature of this structure formation scenario would be a slight blue tilt of the spectrum of gravitational waves. In this paper we give more details of the computations leading to these results, and the assumptions underlying them.
