Title: The multi-wavelength Fundamental Plane in the Fornax Cluster

Abstract: While the Fundamental Plane (FP) is a key constraint on the evolution of early-type galaxies, there are unresolved questions in both the interpretation of the FP and in the measurements of the FP parameters themselves. These issues can be addressed by moving from optical to near-infrared (NIR) observations. We are well underway with constructing the first ever all-NIR FP, with the task remaining to assemble a matched set of homogeneous optical data for direct comparison. We propose here using the CTIO Y4KCam for the necessary optical photometry. The NIR-optical comparison will allow us to look for systematic trends with wavelength and to investigate the driving mechanisms for the tilt and the thickness of the fundamental plane.
