Emergent universe scenario and the low CMB multipoles
arXiv:1312.6877 · doi:10.1103/PhysRevD.91.083534
Abstract
In this work we study superinflation in the context of the emergent universe (EU) scenario. The existence of a superinflating phase before the onset of slow-roll inflation arises in any emergent universe model. We found that the superinflationary period in the EU scenario produces a suppression of the CMB anisotropies at large scale which could be responsible for the observed lack of power at large angular scales of the CMB.
