The challenge of measuring and mapping the missing baryons

TL;DR

This paper discusses the ongoing challenge of locating and characterizing the universe's missing baryons, emphasizing the need for advanced surveys and observational tools to resolve this cosmological issue.

Contribution

It highlights the importance of combining galaxy redshift surveys with new X-ray and radio observations to address the missing baryon problem.

Findings

Potential resolution of the missing baryon problem.

Need for integrated observational approaches.

Uncertainty remains about the physical properties of diffuse 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.
