The cosmic microwave background is the most precise and the most simple cosmological dataset. This makes it our most prominent window to the physics of the very early Universe. In this article I give an introduction to the physics of the cosmic microwave background and show in some detail how primordial fluctuations from inflation are imprinted in the temperature anisotropy and polarisation spectrum of the CMB. I discuss the main signatures that are suggesting an inflationary phase for the generation of initial fluctuations.
Le fond fossile micro-onde est l'ensemble de données cosmologiques les plus précises et les plus simples à interpréter. Ceci en fait notre fenêtre la plus directe sur la physique de l'univers primordial. Dans cet article, je présente une introduction à la physique du fond fossile micro-onde et je démontre comment les fluctuations primordiales de l'inflation se manifestent dans les anisotropies de la température et dans la polarisation du fond fossile. Je discute les principales observables qui présentent des indices importants vers une attribution des fluctuations initiales à une phase inflationnaire.
