Webb Telescope Validates Established Galaxy Theory
A recent study using the James Webb Space Telescope (JWST) has confirmed a longstanding model of galaxy chemical enrichment, highlighting the significant role of asymptotic giant branch (AGB) stars. By analyzing the spectra of three young galaxies, researchers found evidence of elements typically associated with AGB stars, such as carbon, oxygen, vanadium, and zirconium. This supports the theory that AGB stars, particularly thermally pulsing AGBs, are efficient at enriching galaxies, validating a model proposed two decades ago.
