On the origin of the scatter around the Fundamental Plane : correlations with stellar population parameters

We present a fundamental plane (FP) analysis of 141 early-type galaxies in the Shapley supercluster at z=0.049 based on spectroscopy from the AAOmega spectrograph at the AAT and photometry from the WFI on the ESO/MPI 2.2m telescope. The key feature of the survey is its coverage of low-mass galaxies down to σ∼50km s. We obtain a best-fitting FP relation re… CONTINUE READING
