SUMMARY:Properties of dark subhaloes from gaps in tidal streams - Denis Er

DESCRIPTION:In the LCDM paradigm\, Milky Way-like galaxies should be surro
 unded by hundreds of thousands of subhaloes. Many of these subhaloes will 
 be unable to form stars but are still dense enough to survive deep in the 
 potential of their host. Measuring the properties of these subhaloes will 
 provide a key test of LCDM and will put constraints on WDM and more exotic
  theories. In this talk\, I will discuss how the presence and properties o
 f these dark subhaloes can be inferred from their effect on tidal streams.
  Assuming observational errors of ongoing and future surveys\, I will show
  that in the near future it will be possible to constrain these dark subha
 loes down to a mass of 10^7 Msun.
