SUMMARY:A conclusive test of cold dark matter - Carlos Frenk (Durham)

DESCRIPTION:The ``Lambda cold dark matter'' (LCDM) cosmological model is o
 ne of the great achievements in Physics of the past thirty years. Theoreti
 cal predictions formulated in the 1980s turned out to agree remarkably wel
 l with measurements\, performed decades later\, of the galaxy distribution
  and the temperature structure of the microwave background radiation. Yet\
 , these successes do not inform us directly about the nature of the dark m
 atter. Indeed\, there are competing (and\ncontroversial) claims that the d
 ark matter might have already been discovered\, either through the annihil
 ation of cold\, or the decay of warm\, dark matter particles. In astrophys
 ics the identity of the dark matter manifests itself clearly in the proper
 ties of dwarf galaxies\,\nsuch as the satellites of the Milky Way.  I will
  discuss predictions from cosmological simulations assuming cold and warm 
 (in the form of sterile neutrinos) dark matter and show how astronomical o
 bservations can conclusively distinguish between the two.\n
