Sommaire:

Cosmological Inflation is one of the leading paradigms for explaining the
physical conditions that prevailed in the early Universe. It consists in a
phase of very high energy accelerated expansion that solves the hot
big bang model problems. When combined with Quantum Mechanics,
it also provides a causal mechanism for generating cosmological fluctuations
on large scales.

In this talk I will explain how the most up-to-date cosmological observations,
incorporated in the Bayesian model comparison approach, can be used to
extract the favoured models among hundreds of proposed scenarios.
I will insist on the role played by reheating, which connects inflation to
the subsequent radiation era, and during which ordinary matter as we see it
today is produced. I will also discuss some extensions to the
minimal single-field setups, where extra scalar fields are added and play
a role both during inflation and reheating.
