Cracking the Mystery: Astrophysicists Shed Light on the Brightness of Early Galaxies
Astrophysicists from Northwestern University have used simulations to explain the unexpected brightness of early galaxies observed by the James Webb Space Telescope (JWST). The simulations suggest that the galaxies' luminosity is due to bursty star formation, rather than their massive size, aligning with current cosmological models. Bursty star formation occurs when stars form in alternating patterns, with periods of intense star formation followed by periods of few new stars. This finding not only explains the deceptive massiveness of young galaxies but also fits within the standard model of cosmology. The research provides valuable insights into the formation of galaxies during cosmic dawn, a period shortly after the Big Bang.
