SUMMARY:Evolutionary paths of the most massive galaxies since z ~ 2
DESCRIPTION:Evolutionary paths of the most massive galaxies since z ~ 2\nDr
 . Ignacio Trujillo\n\nObservations have shown that massive galaxies at hig
 h redshift have much smaller sizes than galaxies of similar mass today. Th
 e mean stellar density of such objects was almost two orders of magnitude 
 higher than the ones we measured in the most massive nearby galaxies, reac
 hing, in some cases, densities similar to those observed in globular clust
 ers. What is the nature of these objects? And, how these objects have been
  transformed into the present population of massive galaxies? We will summ
 arize the recent findings our group has done on this topic. In particular,
  we will focus on our search for finding relics of these compact galaxies 
 in the nearby universe, and the effort we have done for measuring the evol
 ution of the velocity dispersion of these galaxies in the last 10 Gyr. The
  implications of this research within the galaxy formation scenario will b
 e discussed.\n
