The total mass of a galaxy is a fundamental parameter that drives galaxy evolution. However, the nature of dark matter in early-type galaxies is still very much under debate. Because early-type galaxies do not have large scale HI disks, dynamical masses are often measured using discrete tracers such as globular clusters (GCs) or planetary nebulae, or hot X-ray gas. While some massive ellipticals have high mass-to-light ratios, other intermediate-luminosity ellipticals appear to require little or no dark matter. Current sample sizes for these studies are on the order of a few, and the galaxies studied are in very different environments. We propose to use Gemini/GMOS-N to measure radial velocities of GCs and measure dynamical masses of four sub-L* early-type galaxies in the interesting but unexplored luminosity range -20.5
