Planck was originally proposed to deliver definitive measurements of the temperature anisotropy of the cosmic microwave background on angular scales larger than ~5 arcmin. This goal has been met with the 2015 release of the legacy data set comprising full sky maps of the microwave sky at multiple frequencies. One of the fundamental aspects of cosmology is the precision with which we understand the universe itself, and in particular the nature of the structure-seeding primordial perturbations. More specifically, what do their statistical properties and consistency or otherwise with isotropy reveal about early universe physics?
I will discuss the phenomenological determination of the isotropy and statistics of the large scale structure of the universe from Planck data. This is likely to remain unsurpassed in the foreseeable future.
