Description

Since the launch of the James Webb Space Telescope, observations of the high-redshift universe have opened a new window onto the formation of the first galaxies. These early galaxies appear to undergo bursty star formation, which strongly influences their morphology. However, many large-volume cosmological simulations fail to reproduce these features, highlighting the need to better resolve stellar feedback and star formation. To investigate the origin of these discrepancies, we generate mock observations from SPHINX, a high-resolution cosmological simulation of galaxy formation and ionization in the early universe. By comparing simulated and observed galaxy properties, we explore how star formation shapes galaxy morphology in the first billion years after the Big Bang.
