Rapidly Growing Black Hole in Nearby Galaxy Offers Window into Early Universe
Key Takeaways
- An international team discovered a supermassive black hole in galaxy SDSS J110546.07+145202.4 that has been emitting bright radio waves for eight years, the first such long-duration event observed.
- The black hole is relatively low mass but growing rapidly by accreting matter, triggering a jet that produces the radio emission.
- The event provides a unique window into black hole growth conditions similar to those in the early universe.
- The study combined new and archival data across multiple wavelengths, published in The Astrophysical Journal.
