Constraining the Baryon Fraction in Extragalactic Diffuse Ionized Gas with 124 Localized Fast Radio Bursts
The episode discusses a paper constraining the baryon fraction in extragalactic diffuse ionized gas using 124 localized Fast Radio Bursts (FRBs). The hosts detail how this method overcomes previous limitations by using sophisticated probability distributions and physical models to measure the missing baryons. The findings show the baryon fraction is extremely high, over ninety percent, confirming that most missing baryons reside in this diffuse gas.
