Uncorrelated estimates of the primordial power spectrum
Zong-Kuan Guo, Yuan-Zhong Zhang
We use the localized principle component analysis to detect deviations from scale invariance of the primordial power spectrum of curvature perturbations. With the technique we make…

Reconstruction of the primordial power spectrum from CMB data
Zong-Kuan Guo, Dominik J. Schwarz, Yuan-Zhong Zhang
Measuring the deviation from scale invariance of the primordial power spectrum is a critical test of inflation. In this paper we reconstruct the shape of the primordial power spect…
