How Big Can The Universe's First Starbursts Get?
As our telescopes have improved and we’ve been able to peer farther back in time, we’ve begun finding more fascinating features of the universe. But one thing we definitely haven’t found yet is Population III (Pop III) stars. These were the earliest stars in the universe, formed completely from pristine hydrogen and helium, with no “metals” (i.e. elements heavier than those two) polluting their processes. They are also theorized to be absolutely massive, and “die with passion” as Bill Wurtz once put it in a famous YouTube video. A new paper, available in pre-print form on arXiv by Tae Bong Jeon from the Cosmic Frontier Center at the University of Texas at Austin, looks at just how massive those starbursts could be, and whether the James Webb Space Telescope could detect one.
