Paper Abstract

We present the main results of a project aimed at understanding the nature of extremely red galaxies (ERGs) and their role in galaxy formation and evolution. The paper is focused on recent near-IR spectroscopy of ERGs made with the ESO VLT-UT1 equipped with ISAAC. Neither strong emission lines nor continuum breaks were detected in their near-IR spectra. The optical to near-IR spectral energy distributions of the observed ERGs suggest that 0.8 < z < 1.8 and that most of them are passively evolving elliptical galaxies. The main results of complementary HST and sub mm observations are also presented. Finally, we discuss what the present result tell us about the nature of ERGs and on their relation with the problem of the formation and evolution of elliptical galaxies.
