Abstract

The article discusses the discovery of a significant amount of previously unseen baryonic matter in the intergalactic spaces, utilizing fast radio bursts (FRBs) to probe these regions. Researchers have found that approximately 76% of the universe's normal atomic matter exists as warm gas clouds between galaxies, addressing the long-standing "missing baryon problem." The study, which analyzed a larger sample of 69 FRBs, revealed that this baryonic matter is dispersed rather than concentrated around galaxies, indicating that galaxies expel gas through processes like supernovae and black hole activity. The findings provide insights into galactic feedback mechanisms and set the stage for future research on the cosmic web of gas connecting galaxies. [Extracted from the article]
