What is a typical mass density for inter-galactic gas in a cluster?

Click For Summary
SUMMARY

The typical mass density for inter-galactic gas in a cluster is approximately 1 atom per cubic meter, as determined through X-ray emission detections, particularly illustrated by the bullet cluster images. This finding is supported by research available at Harvard's Center for Astrophysics, which provides insights into the intergalactic medium. Additionally, discussions highlight the importance of precise search queries, such as "mass density of galaxy cluster gas," to yield relevant academic papers and data.

PREREQUISITES
  • Understanding of X-ray emission detection methods
  • Familiarity with the concept of intergalactic medium
  • Knowledge of astrophysical research methodologies
  • Ability to interpret scientific papers in astrophysics
NEXT STEPS
  • Research X-ray emission detection techniques in astrophysics
  • Explore the properties and significance of the intergalactic medium
  • Study the bullet cluster and its implications for cosmology
  • Learn how to effectively search for scientific literature using precise queries
USEFUL FOR

Astronomers, astrophysicists, and students interested in cosmology and the study of inter-galactic gas density will benefit from this discussion.

TL;DR
As far as I'm aware, galaxy clusters typically have some level of hot gas permeating the entire cluster, which the galaxies within these cluster orbit each other within. What is the typical mass density of that gas?
I assume we can work it out from X-ray emission detections, such as shown with the famous bullet cluster images.

OMG, thank you. I tried searching for "mass density of galaxy cluster gas" and variations but never intergalactic gas. The results I found focused on electron density and I struggled to understand the papers e.g. https://academic.oup.com/mnras/article/457/1/281/989241

Clearly I need google my exact question before posting it. Thank you again!
