The team interpreted those shifts as the effect of cyclonic winds moving above and below the black hole at speeds of about 4000 kilometers per second, tens of thousands of times stronger than the most intense cyclones on Earth.
Previously, astronomers have used x-ray telescopes to observe strong winds very near the massive black holes at galactic centers (artist's concept, inset) and infrared wavelengths to detect the vast outflows of cool gas (bluish haze in artist's concept, main image) from such galaxies as a whole, but they've never done so in the same galaxy.
Astronomers have observed tornadolike winds powered by a central active supermassive black hole, such as the one in this image, pervading a galaxy.
Big stars with low metal content don't shed as much of their mass over time, so when one of them dies, almost all of its mass will wind up in the black hole.
