SUMMARY:Cosmological giants and elves: galaxy formation and the small scale
  of cold dark matter
DESCRIPTION:Cosmological giants and elves: galaxy formation and the small s
 cale of cold dark matter\nProf. Julio Navarro\n\nI will review the status 
 of our understanding of galaxy formation in the prevailing cold dark matte
 r paradigm. After reviewing the successes and failures of the most natural
  predictions of this scenario I will focus on the consequences of two of i
 ts main predictions: the presence of large numbers of low-mass dark matter
  halos and the prevalence of accretion events during the formation of norm
 al galaxies. In particular, I will discuss the interpretation of the recen
 t discovery of a population of ultra-faint galaxies in the Local Group, an
 d its relation to the profuse cold dark matter substructure expected in th
 e Galactic halo. I will also discuss the importance that accretion events 
 might have had in shaping not only the stellar halo but also the disk comp
 onent(s) of the Milky Way.
