Physics Colloquium - Dr. Krzysztof Turzynski Presenting Cosmology as a Branch of Particle Physics
Observations of the Universe provide us with ample evidence that the Standard Model of particle physics needs to be extended. Galaxy rotation curves, dynamics of galaxy clusters and the properties of the cosmic microwave background can be explained by extending the particle spectrum with massive particles which do not interact with light - dark matter particles. Abundances of light elements are consistent with primordial nucleosynthesis and the properties of the cosmic microwave background given that there is a precisely determined excess of matter over antimatter which cannot be explained within the Standard Model. The distribution of large structures in the Universe and the properties of the cosmic microwave background hint at the possibility that the hot Universe was preceded by rapidly accelerating - inflating - Universe.
Attempts to describe all these phenomena with tools of particle physics require going beyond the Standard Model. During almost two decades of my career as a physicist I have had the privilege to contribute to each of the three aspects of cosmology described above. Based on this experience, I will provide a personal and subjective review of the progress that has been made in that time.
