Near – Infrared Imaging of Early – Type Galaxies IV . The Physical Origins of the Fundamental Plane Scaling Relations

Abstract

The physical origins of the Fundamental Plane (FP) scaling relations are investigated using large samples of early–type galaxies observed at optical and near–infrared wavelengths. The slope a in the FP relation reff ∝ σ a 0〈Σ〉 b eff is shown to increase systematically with wavelength from the U–band (λ ∼ 0.35μm) through the K–band (λ ∼ 2.2μm). A distance… (More)
