SUMMARY:Astrophysical probes of dark matter 
DESCRIPTION:Astrophysical probes of dark matter \nProf. Justin Read\n\nDark
  matter makes up most of the mass of the Universe but remains  mysterious.
  I discuss recent progress in constraining its properties by  measuring it
 s distribution in the Universe from tiny dwarf galaxies to  giant galaxy c
 lusters, and comparing this with numerical simulations.  The latest result
 s favour a cold, collisionless particle that must lie  beyond the standard
  model of particle physics. I discuss the known small  scale problems with
  this model: the cusp-core and missing satellites  problems, and I argue t
 hat these are likely due to baryonic "feedback"  during galaxy formation. 
 I conclude with a discussion of experiments  underway to detect dark matte
 r particles, and the role that astrophysics  has to play in these too. The
 re is an exciting a very real prospect of  detecting a dark matter particl
 e in the next five years.
