Prof Dave Hanes, Queens Univ. Canada A Talk in Two (Brief) Parts: 1) SNO / SNOLAB: An Astronomical Appreciation 2) Dynamics of Globular Cluster Systems in Early-Type Galaxies Queen's University is the headquarters of the multi-national Sudbury Neutrino Observatory (SNO). This renowned experiment has completely resolved the long-standing Solar Neutrino Problem, with results that require nothing less than a wholesale revision of the standard model of particle physics. The heavy-water-based SNO experiment has now ended, and the deep underground site is being enormously extended and readied for a suite of dark-matter detection experiments of considerable astrophysical interest, in the newly-dubbed SNOLAB facility. As the Head of my Department, I have been privileged to watch these developments with an astronomer's passion but (it must be admitted) without the very deep technical understanding enjoyed by my particle physics colleagues. I will present a brief but non-technical discussion and appreciation, well illustrated, of the accomplishments and promise of SNO / SNOLAB. I will describe to you the enormous engineering challenges represented by the construction of this kind of facility at enormous depth in the Sudbury mines of Northern Ontario. In the second part of the talk, I will describe some of our ongoing research into the dynamics of globular cluster systems in early-type galaxies, with important implications for galaxy formation and interaction histories. We will see that four-metre telescopes equipped with multi-spectroscopic instrumentation can still play an important role in this competitive research area.
