报告摘要:The standard $\Lambda$CDM cosmology model has been a great success in explaining the plethora of observational data, with the exception of very few anomalies that are mostly found in the cosmic microwave background (CMB). I will discuss the updated CMB anomalies in the Planck Satellite 2015 Isotropy and Statistics paper (released in June 2015) and present our novel statistical tools (zoom-in inpainting and oriented stacking) that can be used to visualize and statistically test the anomalies.
