The Universality of the Fundamental Plane for Galaxies and Galaxy Systems: M/L
Abstract
We present the results of a comprehensive study of the fundamental plane (FP) for stellar systems and galaxy systems. We have searched for variations of the FP and the mass-to-light ratio at different scales, which are indicative of variations in the Dark Matter distribution as a function of the scale. For this aim, we have analyzed in a homogeneous way data from objects whose scales varies from globular clusters to clusters of galaxies. We found that the mass-to-light ratios changes along the different scales. Therefore we suggest that groups dark halos are lost when they are incorporated into clusters of galaxies.
