Relic galaxies: where are they?
  The finding that massive galaxies grow with cosmic time fired the starting
gun for the search of objects which could have survived up to the present day
without suffering substantial changes (neither in their structures, neither in
their stellar populations).
  Nevertheless, and despite the community efforts, up to now only one firm
candidate to be considered one of these relics is known: NGC 1277. Curiously,
this galaxy is located at the centre of one of the most rich near galaxy
clusters: Perseus. Is its location a matter of chance? Should relic hunters
focus their search on galaxy clusters?
  In order to reply this question, we have performed a simultaneous and
analogous analysis using simulations (Millennium I-WMAP7) and observations (New
York University Value-Added Galaxy Catalogue). Our results in both frameworks
agree: it is more probable to find relics in high density environments.
