In the 1990's, cosmology has evolved into a mature, detailed science pushed forward by an enormous amount of observational data. Bond, Knox, and Souradeep have been studying how well one can reconstruct the primordial power spectra and the inflation potential from measurements to be done with Plank and MAP, while Bond, Pogosyan, and Souradeep have developed a completely general method for calculating CMB anisotropy in models with non-trivial topology. Cosmologists at CITA are building new tools and techniques for interpreting the coming deluge of new CMB data.
CITA researchers are also involved with the experiments themselves.
Tophat balloon-borne experiment to measure CMB anisotropy and is also involved in analysis of the Python data set taken by the south pole telescope. The size and depth of galaxy redshift surveys will increase dramatically in the next few years and new statistics on the large-scale distribution of galaxies will be available for direct comparison to cosmological theories. The main problems that are being tackled with these codes are the evolution of the Lyman- forest, the formation of galaxy clusters, and the study of galaxy interactions in merging pairs and in clusters.
