Why Are Supermassive Black Holes Growing So Slowly?
#supermassive black holes #galaxy evolution #gas accretion #astronomical research #cosmic growth
📌 Key Takeaways
- Supermassive black holes at galaxy centers are growing slower than expected.
- New research suggests limited gas accretion may be a key factor.
- Observations indicate many black holes are in a dormant or low-activity state.
- This slow growth challenges previous models of black hole evolution.
- Findings could impact understanding of galaxy formation and cosmic history.
📖 Full Retelling
About 10 billion years ago, the growth rate of supermassive black holes began to slow dramatically. To this day, the SMBH growth rate still appears to be low. There are three potential explanations for this, and researchers think they've figured out which explanation fits best.
