• super-inflation
• bounce
• low multipole anomaly

In this paper we present a simple argument that shows a non-singular bouncing cosmology naturally yields an era of super-inflation which can precede the phase of normal potential driven inflation. One of the consequences of a super-inflation phase is that it might be able to account for suppressing the low multipole in the amplitude of the cosmic microwave background radiation. We estimate that the number of e-folds of super-inflation required to explain the current Planck data to be roughly three e-folds.
