Astronomers, using NASA’s James Webb Space Telescope (JWST) and the Chandra X-ray Observatory, have discovered a low-mass supermassive black hole LID 568.
LID-568 Black Hole:
- About:
- LID-568 is a low-mass supermassive black hole that existed 1.5 billion years after the Big Bang.
- It was discovered through X-ray and infrared observations and is located in a galaxy with minimal star formation, likely due to the black hole’s powerful outflows.
- Key Features:
- Super-Eddington Accretion: It feeds at a rate 40 times the Eddington limit, which is the maximum rate at which a black hole or star can accrete matter without radiation pressure pushing matter away.
- Eddington Limit represents the balance between gravitational pull and outward radiation pressure, preventing further accretion if exceeded.
- Galaxy Effects: The black hole’s outflows prevent the accumulation of matter needed for star formation in its galaxy.
- Super-Eddington Accretion: It feeds at a rate 40 times the Eddington limit, which is the maximum rate at which a black hole or star can accrete matter without radiation pressure pushing matter away.
- Significance:
- Challenges Current Models: LID-568’s rapid growth contradicts theories requiring sustained accretion for supermassive black hole formation.
- Insights into the Early Universe: It suggests that short bursts of intense feeding could explain the formation of large black holes in the early universe.
- Future Research: Opens avenues for studying black hole accretion processes and their impact on galaxy evolution.
