Astronomy 627: Cosmology

  • The observational context: Cosmic Microwave Background Radiation, Hubble expansion, galaxies, dark matter, clustering properties of galaxies, large-scale structure, peculiar velocities,  deviations from isotropic Hubble flow, light element abundances
  • The theory of gravitation: Difficulties with Newtonian gravitation, Mach's Principle, isotropic curved spaces, special relativity, 4-vectors, covariant formulation of electrodynamics, outline of general relativity, Einstein field equations.
  • The "standard" cosmological models: Cosmological principles, Robertson-Walker metric, measurements of distances, luminosities, angular sizes,  Friedman models,  anthropic principle and Dirac's large numbers
  • Thermal history of the Universe: Radiation-dominated expansion, recombination,
    fluctuations
  • Big-Bang Nucleosynthesis: Nuclear statistical equilibrium in the early Universe, light element synthesis, baryon and lepton asymmetry
 
  • Inflationary cosmology: Expansion, flatness, horizon, equation of state,  fluctuation spectrum
  • Galaxy formation: Jeans' instability, growth of density perturbations,, dissipation processes, fluctuations in baryonic and non-baryonic matter, hot and cold dark matter models,  measured clustering spectra, peculiar velocity fields
  • CMB Fluctuations: gravitational, adiabatic, and Doppler perturbations, multipole expansion, angular structure, re-heating, Sunyaev-Zeldovich Effect, anisotropies
  • Evolution of galaxies:Non-linear collapse of density perturbations, hierarchical clustering, source counts, background radiation
  • Evolution of star formation rates and element abundances: Lyman-alpha clouds, star-forming galaxies out to large redshifts, cosmic chemical evolution
