Astronomers have identified a universal rule regarding black hole jet formation, noting that both supermassive and stellar-mass black holes launch radio jets when their feeding rate drops to approximately 2% of the Eddington limit. Researchers utilized tidal disruption events to observe these processes in real-time, confirming consistent physics across a mass range spanning seven orders of magnitude.

Further research has explored the impact of supermassive black holes on galactic evolution. Studies suggest that jets of ionized gas emitted by these black holes transport material to the outer edges of galaxies, affecting the circumgalactic medium and potentially preventing gas from cooling to form new stars. Concurrently, efforts are underway to locate isolated stellar-mass black holes within the Milky Way using Gaia DR3 data.

### 2026-09-21: Black hole jet formation follows universal rule across all masses

New research suggests black hole jet formation follows a universal rule, occurring at a specific feeding threshold regardless of whether the black hole is stellar-mass or supermassive.
