Abstract

During the last three decades, cosmology has undergone a transition from a theory-dominated discipline to a data-driven science. Currently, numerous Earth and space-based experiments provide observers with a continuous flow of high precision data, allowing us to constrain and rule out many of the models brought forward by theorists. For the first time, we have the tools to study in an accurate and quantitative way the origins and evolution of the Universe. It is unsurprising that our present days are commonly referred to as the era of precision cosmology. In this picture, the bispectrum of the cosmic microwave background has emerged as a powerful observable to discriminate between models of the early Universe. This short chapter is meant to familiarise the reader with the subjects that will be treated in depth in the rest of the thesis.
