Yeah they have the LyA forest data in their model and their model’s fit is poor by eye. Do you know why the uncertainty for those has an upper limit but no lower one on the graph? Is there commonly no lower limit to the constraints derived from LyA forests?

FYI the article is suspicious, there is not really a physical mechanism proposed and the galaxy sample they use seems cherry-picked to give them the two populations the authors want. This is not five sigma science.
