Potential science for the OASIS integral field spectrograph with laser guide star adaptive optics

I review the science case for the Laser Guide Star system being built for the William Herschel Telescope on La Palma. When used in combination with the NAOMI Adaptive Optics system and the OASIS visible-wavelength Integral Field Spectrograph, I demonstrate that there are substantial, exciting areas of astrophysical research in which the WHT can contribute.
