Colloquium: Precision cosmology as a probe of particle physics

ABSTRACT

Precision observations of the cosmic microwave background (CMB) and the large-scale distribution of matter has in the past two decades provided us with a wealth of information about the structure and energy content of the Universe, including dark matter and dark energy.  In this talk I will discuss what we have learnt so far, how present and future CMB observations and galaxy surveys can be used to probe particle physics, as well as the challenges that must be overcome to maximise the information gain.
