Scientists Measure a Black Hole's Jet Power for the First Time
The jets carry about 10% of the energy released as matter falls toward the black hole, researchers said.
- On Thursday, researcher Steve Prabu reported the first-ever measurement of instantaneous jet power and speed from Cygnus X-1 using 18 years of high-resolution radio imaging data from a global telescope network.
- Cygnus X-1, a binary system in the Cygnus constellation, features a black hole pulling gas from a blue supergiant star that feeds the black hole, giving it "something to eat" and launch as jets, Prabu said.
- Jet power is equivalent to 10,000 suns, with speeds reaching roughly 355 million mph, while these "dancing jets" carry approximately 10% of the energy released as matter falls toward the black hole.
- Previously, jet power estimates relied on averaging data over tens of thousands of years; this direct measurement technique, based on computer modeling and wind-driven jet bending, enables instantaneous observations.
- Prabu plans to apply this technique to other black holes, building on work conducted at Curtin University, as better jet power data helps scientists understand how black holes shape galaxies through large-scale turbulence.
