Infinity Galaxy Discovery Reveals Rare Supermassive Black Hole Origins, Challenges Existing Theories
  • Scientists have discovered a rare ring-shaped galaxy duo called the Infinity Galaxy, which appears to host a supermassive black hole formed through direct collapse, offering new insights into black hole origins.

  • This discovery was made by analyzing data from the COSMOS-Web survey and conducting follow-up observations with NASA's James Webb Space Telescope and other observatories.

  • The JWST observations of the Infinity Galaxy provide valuable clues about the formation of supermassive black holes, especially in the context of the early universe.

  • Researchers plan to measure the velocities of the black hole and surrounding gas to determine if the black hole originated from that gas or if it was formed elsewhere.

  • Preliminary data shows the black hole's velocity closely matches that of the surrounding gas, supporting the idea that it formed from local gas rather than being a runaway or from another galaxy.

  • While not yet definitively confirmed, the evidence strengthens the case for a newly formed black hole, challenging some existing theories and prompting further investigation.

  • Van Dokkum notes that such galaxy collisions are rare but may have been common in the early universe, potentially leading to black hole formation.

  • The findings support the 'heavy seeds' theory, suggesting that massive black holes can form from large gas clouds collapsing during galaxy collisions, as observed in the Infinity Galaxy.

  • This discovery challenges the 'light seed' theory, which posits that black holes grow over billions of years through mergers of smaller black holes, by providing evidence of rapid formation.

  • Researchers propose that the black hole formed from a gas cloud compressed during the collision, leading to a direct collapse about 50 million years ago, which has since grown significantly.

  • Van Dokkum describes this as close to a 'smoking gun' for understanding black hole origins, especially given the black hole's unusual placement between the colliding galaxies rather than within their nuclei.

  • The black hole, located between the two colliding galaxies and feeding on gas, represents the first observational evidence of the direct collapse pathway of black hole formation.

  • This is the first time a newly formed black hole has been observed outside a galaxy's nucleus, providing a potential direct observation of black hole birth.
