Researchers Measure the Environment Where the First Supermassive Black Holes Formed
Astronomers are investigating how supermassive black holes formed so early in the universe, challenging traditional star-collapse models. The research focuses on the 'Direct-Collapse' scenario, where massive gas clouds in dense cosmic environments form black hole seeds.
Why it matters
Advances our fundamental understanding of the early universe and the origins of the largest structures in space.
When the James Webb Space Telescope pointed its powerful instruments toward the early Universe, scientists were surprised by what it found. At high-redshift (z) values, corresponding to less than one billion years after the Big Bang, astronomers witnessed an abundance of galaxies that hosted what appeared to be the "seeds" of supermassive black holes (SMBHs). The existence of such massive black holes so early in the Universe challenged existing models of black hole formation, in which stars collapse at the end of their lives to form black holes that gradually come together to create SMBHs.
