Galaxies, Globular Clusters, and Dark Matter

Abstract

This is an autobiographical account of my scientific career. My main research interest is the structure and assembly of galaxies. The assembly narrative has evolved from the monolithic and baryonic collapse picture of the early 1960s to the current hierarchical scenario underpinned by dark matter, and is still evolving. Technology has changed: CCDs replaced photographic plates and image tubes, large optical telescopes are much larger and instruments are much better, Galactic archaeology is supported by vast stellar surveys, and we have space astronomy and radio synthesis telescopes. The article describes the scientific areas in which I have worked and the colleagues who have influenced my progress. I have much to be grateful for: the people who have mentored and supported me over the years, the privilege of long-term collaborations, and the pleasure of advising many Ph.D. students and postdocs.
