Baryonic Dark Matter and Machos

  • Kim Griest
Conference paper

Abstract

A brief inventory of baryons in the Universe is given, along with results from the MACHO collaboration and their various interpretations. A dark matter halo consisting of baryons in the form of Machos is ruled out, leaving an elementary particle as the prime candidate for the dark matter. The observed microlensing events may make up around 20% of the dark matter in the Milky Way, or may indicate an otherwise undetected component of the Large Magellanic Cloud. Several new pieces of work lend support to both possibilities, leaving the answer uncertain.
