How Supermassive Black Holes Grew So Fast in the Early Universe

from Bedtime Astronomy · host Synthetic Universe

New research from Maynooth University sheds light on how supermassive black holes formed so quickly after the Big Bang. Advanced simulations show that small “light seed” black holes can grow rapidly through super-Eddington accretion in dense, gas-rich young galaxies.This process removes the need for exotic origins and fills a key gap in our understanding of galaxy evolution, with important implications for future gravitational-wave discoveries.Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes on space exploration, NASA missions & the latest astronomy breakthroughs.
