Maths HEP Lunchtime Seminars: Primordial Fluctuations and the Cosmological World Model

Presented by "Shaun Cole (Durham)",

1 March 2002 13:00 in CM221

"Only in recent years has it become possible to directly measure density fluctuations on sufficiently large scales that they can be directly related to primordial fluctuations. Accurate measurement have now been made of fluctuations in the Cosmic Microwave Background and in the distribution of galaxies of very large scales. I will quickly review the current understanding of the origin of these fluctuations, with emphasis on how the assumed cosmological model and material content of the universe effects their evolution. I will then introduce the "2dF Galaxy Redshift" survey which is the largest existing 3D survey of the local universe. I will show how we are using this to probe the primoridal spectrum of fluctuations and hence constrain the material content and the cosmological world model parameters of our universe.
