Galaxy Formation and Cosmology

The rapid progress in observational measurements of anisotropies in the
cosmic microwave background means that we now understand the global
structure and matter content of the Universe to good precision. One of the
main goals of cosmology now is to understand how those anisotropies grow
into the objects we see in the Universe today, namely galaxies. I will describe
how our understanding of galaxy formation as a cosmological process is progressing,
highlighting recent results in the areas of galaxy clustering and the origins
of dwarf galaxies and will examine the possible existence of dark galaxies.
