Sommaire:

Today, the Cosmic Microwave Background (CMB) is one of the most powerful observable to understand cosmology.
Cosmic inflation, a speculative era of primordial accelerated expansion, is the most popular very-early-universe theory that is able to explain these observations.

I will discuss the CMB and the standard model of cosmology, before presenting the status of the CMB-anisotropies measurements and how well they are able to constrain our model.
I will then focus on the future of CMB-anisotropies measurements, introducing the next-decade experiments and their forecasted constraints on our models.

I will also discuss the simplest class of inflation phenomenology, that only needs introducing a scalar field slowly rolling on its potential.
I will show the current and future constraints on this specific type of inflation realisation, before presenting how to embed such a model in a well-defined particle-physics framework, based on arXiv:2304.04534.
