SUMMARY:Shedding Light on Dark Matter: How Faraday Rotation Can Limit 
 a Dark Magnetic Moment\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, S
 usan Gardner\, University of Kentucky
DESCRIPTION:Disparate astronomical observations provide compelling evi
 dence for additional\, non-luminous matter\, or dark matter\, in gravi
 tational interactions\, but we know little of its nature. To remedy th
 is\, the hunt is on to detect dark matter via either direct or indirec
 t means\, to determine its mass(es?) as well as couplings to Standard 
 Model particles. I will briefly review the astronomical evidence and s
 ummarize current direct and indirect detection efforts before describi
 ng a new possibility. That is\, a Faraday rotation experiment can set 
 limits on the magnetic moment of a electrically-neutral\, dark-matter 
 particle\, and the limits increase in stringency as the candidate mass
  decreases. I shall describe how such could be realized and determine 
 the limits on the magnetic moment as a function of mass which follow g
 iven demonstrated experimental capacities.
