✦ Synopsis

We have undertaken a programme on the Gemini 8-m telescopes to demonstrate the power of integral field spectroscopy, using the CIRPASS instrument in the near-infrared. Here, we present some of our results from 3D spectroscopy of extra-galactic objects: mapping the Ha velocity field in a z % 1 disc galaxy; exploring dark matter sub-structure through observations of an Einstein cross gravitational lens; and the star formation time-scales of young massive clusters in a starburst galaxy.

Studies of globular cluster systems play a critical role in our understanding of galaxy formation. Imaging with the Hubble Space Telescope has revealed that young star clusters are formed copiously in galaxy mergers, strengthening theories in which giant elliptical galaxies are formed by the merger
