Cosmology & Early Universe
Over the past decade, cosmology has evolved into a mature, detailed science pushed forward by an enormous amount of observational data. Research in cosmology at CITA covers most areas of current interest including studies of the early universe and the origin of the primordial density fluctuations, the connection to the cosmic microwave background (CMB) temperature fluctuations and the nonlinear evolution via gravitational collapse into galaxies, clusters of galaxies and large-scale structure.
