Key Takeaways
1. Researchers discovered the Infinity Galaxy, formed from the collision of two galaxies, using data from the James Webb Space Telescope.
2. An active supermassive black hole was found floating between the two galaxies, rather than at their centers.
3. This black hole supports the heavy seed theory of black hole formation, suggesting massive gas clouds can collapse directly into giant black holes.
4. Observations show the black hole’s speed matches the gas cloud’s speed, indicating it likely formed in its current location rather than being expelled from another galaxy.
5. The Infinity Galaxy is unique as it hosts three active supermassive black holes, including those in both original galactic nuclei.
Researchers who are looking at public data from the James Webb Space Telescope have stumbled upon a peculiar object called the Infinity Galaxy. It seems to be the outcome of a direct collision between two galaxies. An even more astonishing find was made — an active, supermassive black hole that’s not located in the center of either galaxy, but instead floating in the large volume of gas that lies between them.
New Insights on Black Hole Formation
This black hole, which is not at the center, could be the strongest evidence for the heavy seed theory regarding the formation of black holes. This idea suggests that a huge cloud of gas can collapse directly into a giant black hole. This process might explain how the massive black holes spotted by Webb in the early universe became so large at such a rapid pace.
“We believe we are observing the creation of a supermassive black hole – something never seen before,” says Pieter van Dokkum from Yale University, who is the main author of a paper discussing this discovery.
Confirming the Findings
The research team utilized Webb to carry out additional observations to verify their theory. The fresh data indicated that the speed of the black hole aligns perfectly with the speed of the gas cloud around it. This crucial finding makes it very unlikely that the black hole is a runaway object that was expelled from another galaxy; rather, it strongly hints that it formed right there from the collapsing gas.
To make this discovery even more remarkable, the researchers also found out that both of the initial galactic nuclei have their own active supermassive black holes. This makes the Infinity Galaxy a unique system, hosting three such black holes. While the team notes that they cannot definitively assert they have found a black hole formed by direct collapse, they mention that the new data bolsters their argument while ruling out other possible explanations.
