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

AI Thread Summary
The typical mass density for inter-galactic gas in a cluster is approximately 1 atom per cubic meter, as derived from X-ray emission detections, particularly illustrated by the bullet cluster images. The discussion highlights the importance of using precise search terms, as many results focus on electron density rather than mass density. The participant expresses gratitude for the clarification and acknowledges the need for better search strategies. Overall, the conversation emphasizes the challenges in finding specific scientific data and the value of accurate terminology in research. Understanding inter-galactic gas density is crucial for astrophysical studies.

TL;DR Summary
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!

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
