Emergent Universe Scenario and the Low CMB Multipoles

Abstract

In this paper, based on Phys. Rev. D 91, no. 8, 083534 (2015), we study super inflation in the context of the Emergent Universe (EU) scenario. The existence of a super inflating phase before the onset of slow roll inflation arises in any Emergent Universe model. We found that the super inflationary period in the EU scenario produces a suppression of the CMB anisotropies at large scale which could be responsible of the observed lack of power at large angular scales of the CMB.
