The /1CDM paradigm for structure formation in the Universe, described in many hundreds of published papers, is very effective at reproducing observed large scale structure, based on a boundary condition of a scale-free Gaussian random power spectrum. Yet ACDM contains no information on the physics of whatever makes up CDM, and remains deficient in its description of galaxies and small-scale structures thus it is on galaxy scales and smaller where we can still learn the most, and hopefully attach some (astro-)physics to an ab initio power spectrum. 

The halo globular cluster system also provides valuable information, since accurate distances, and hence reliable ages, can be derived. Mackey Gilmore (2004) recently acquired and compiled a new, nearly complete, internally consistent set of photometric studies of the globular cluster population in both the Milky Way and its satellite galaxies they deduce, from analysis of HB morphol-ogy, age, abundance and structural information, somewhat more relaxed limits...

A fine account of the structure and content of galaxies is given in Mihalas and Binney (1981) and excellent introductions to many questions in GCE are to be found in Truran and Cameron (1971) and Tinsley (1980). A good modern account of the kinematics and abundance distribution of the Galaxy is given by Gilmore, Wyse and Kuijken (1989).
