The challenge of measuring and mapping the missing baryons

Abstract

The missing baryon problem may now be resolved, but the exact location and physical properties of the diffuse component remains unclear. This problem could be tractable, but requires the combination of new galaxy redshift surveys with new X-ray and radio facilities.
