The Properties of Faint Galaxies in Nearby Clusters of the WINGS Sample

We present the results of our X-shooter observations for a sample of dwarf (\(-17 < M_{B} < -15\)) galaxies in nearby (0. 040 < z < 0. 068) galaxy clusters of the WINGS sample. The study of galaxies in this faint luminosity range is fundamental to trace the evolution of high-z star-forming cluster galaxies down to the present day. We measure the velocity dispersion of 22 galaxies in this range of luminosity and we explore their scaling relations. We found that the Fundamental Plane has a peculiar feature, suggesting the existence of some kind of warping at low luminosities.
