"Black Holes: From Star Creation to Star Quenching"

New findings from the James Webb Space Telescope (JWST) suggest a shift in the understanding of galaxy formation, indicating that supermassive black holes may have formed alongside the first stars and initially promoted their growth through positive feedback. However, about a billion years after the Big Bang, these black holes transitioned to a mode of quenching star formation through negative feedback, depleting gas reservoirs in galaxies. This discovery challenges conventional theories and provides a new timeline for early galaxy formation, potentially guiding future observational strategies and computer simulations to validate this novel process.
