Introduction: discovery of galaxies, distance scales, redshifts and the expansion of the universe. Galaxy types: morphology; infra-red radio and X-ray observations, luminosities, sizes and surface brightness, galaxy environments structure of ellipticals, structure of spirals. Stars in galaxies: stellar types, lifetimes, stellar populations, stellar mass function, evolution. Gas in galaxies: neutral hydrogen, HII regions, molecules, gas distributions, dust, star formation. Galaxy dynamics: rotation and velocity dispersion of ellipticals, virial theorem, Faber-Jackson relation, supermassive black holes, rotation of spirals, rotation of the Galaxy, Tully-Fisher relation, Galactic halo, Galactic Centre, dynamical evolution. Galaxy formation and evolution: galaxies at high redshift - observations, galaxies at high redshift - theory.
