The Physics of Dark Matter

A wealth of astrophysical and cosmological observations points towards the existence of a new form of matter, called Dark Matter, which gravitates but has little or no interaction with electromagnetic radiation. Observational and theoretical constraints exclude all known particles as constituents of this mysterious Dark Matter, but still allow very large ranges of mass and interaction strength of these particles. In this talk I will review the evidence for Dark Matter and mention a couple possible candidate particles and the resulting phenomenology.
