Primordial standard clock models and CMB residual anomalies

The residuals of the power spectra Wilkinson Microwave Anisotropy Probe and Planck's cosmic microwave background (CMB) anisotropies data are known to exhibit a few interesting anomalies at different scales with marginal statistical significance. Combining bottom-up top-down model-building approaches using pipeline that efficiently compares model predictions data, we construct primordial standard clock is able link address both large small scales. This model, its variant, provide some best fits feature in CMB. According Bayes evidences, these models currently statistically indistinguishable from Standard Model. We show difference between them will soon become significant various higher quality on CMB polarization. demonstrate such data-analyses process may be used uncover portion detailed evolutionary history our universe during epoch.
