Cosmology
An MIT OpenCourseWare graduate course in astrophysical cosmology, covering the Cosmic Microwave Background radiation, galaxy formation and phenomena at high redshift, and the growth of cosmic structure. Additional topics include cosmic inflation, nucleosynthesis and baryosynthesis, quasar absorption lines, and gamma-ray bursts. Some background in general relativity is assumed. Materials include lecture notes, problem sets, and readings drawn from MIT's physics curriculum, published under a Creative Commons license as part of OpenCourseWare. There is no instructor interaction or certificate, but the full set of course materials is freely downloadable for self-study. The course suits students who already have a foundation in general relativity and want a structured path through modern observational and theoretical cosmology.
