This volume investigates the state of theoretical and observational cosmology following the initial data release from the Planck mission. The text compiles lecture notes from the 100th Les Houches Summer School, featuring contributions from experts such as Cédric Deffayet, Patrick Peter, and Benjamin Wandelt. It provides a pedagogical framework for understanding the implications of Planck satellite data on current models of the early universe and large-scale structure.

Experts and researchers in the field of theoretical physics utilize this volume as a foundational reference for understanding the immediate impact of the Planck mission. Readers frequently note the high academic density and technical rigor of the prose, which is intended for graduate-level students and professional physicists.
