## Summary and Conclusions 

The research activity and success that has occurred within the field of Cos- mology over the last several decades, both observationally and theoreti- cally/computationally, is vast. We have reached a point in which the amount of data being obtained observationally, as well as its precision, is of a suf- ficient level to strongly guide the direction that theoretical topics within Cosmology should take. This era of “Precision Cosmology” is, for example, having an ever-greater input into the topic of Inflation. It has the power to rule-out with high confidence certain models of Inflation, whilst giving further (strong) support to others. 

The momentum that Cosmology research is experiencing at the moment is not just down to the field of Cosmology however. Several other fields are providing significant input into Cosmology, the main one being, at least for our work, particle physics. The topics of QFT and, in general, the Standard Model of particle physics play key roles in the development of modern Par- ticle Cosmology.
