Description

We discuss cosmic microwave background anisotropies in models with an unconventional primordial power spectrum. In particular, we consider an initial power spectrum with some 'spiky' corrections. Interestingly, such a primordial power spectrum generates 'wavy' structure in the CMB angular power spectrum
