  The mystery of ellipticals - Symposium 4 at EWASS 2013 (Monday-Tuesday, July 8-9th, 2013)

Aim of the Symposium:

     Numerous detailed observations over the last decade have confirmed the existence of a spectacular population of
     massive and extremely compact quiescent galaxies at redshifts of z~2, which has no present day counterpart.
     Their descendants underwent significant structural evolution (size growth by a factor of 3-5, decrease of the effective
     stellar densities by several orders of magnitude, changes in the mass distribution) and are now, most likely, part of the
     local early-type galaxy (ETG) population. At this Symposium we intend to bring together world leading experts to report
     and discuss the most recent observational and theoretical aspects of the structural evolution of early-type galaxies
     focusing on the following two topics:  

  • Properties of compact early-type galaxies at z~2 and their evolution with redshift
    What are the best current observational constraints on the typical sizes, shapes, masses and velocity dispersions of these
    galaxies? How common are they compared to the general z~2 galaxy population? What is known about their evolution towards
    the present day? What are the observational constraints on merger rates? What are their progenitors at higher redshift? What
    type of galaxies are the local descendants of the compact massive early-type galaxies? Is there a population present day counterparts
    and what are their properties?
  • Theoretical implications for theories on ETG formation
    How did the compact massive galaxies form? What physical mechanisms can explain the observed size growth? Are there alternatives
    to minor merging? What are the observable consequences for the different formation scenarios and what are the best observational tests?
    What remains of the traditional models for ETG formation (spiral mergers, monolithic collapse)?
