Black holes can blast their surroundings with much stronger winds than previously thought, scientists say.The discovery will help better model the evolution of black holes over time, and help uncover the huge influence they can have on their host galaxies.Black holes are objects with gravitational pulls so powerful, not even light can escape. Black holes grow when gas and dust in space flows or accretes onto them — this matter gets so hot it glows hot with radiation such as X-rays.The amount of radiation flowing out from a black hole cannot exceed a certain level known as the Eddington limit or this radiation will blow gas flowing inward away. This limit is based on the black hole's mass.
However, whether the amount of kinetic energy from a black hole, in the form of jets and winds, was constrained by the same limit was unclear. Insights on these jets and winds is crucial for understanding the critical role black holes can play in their host galaxies — for instance, they could blow on gas hard enough to keep stars from forming.To help solve this mystery, scientists investigated the black hole called MQ1 at the center of its host galaxy, M83, for more than a year. The galaxy lies about 15 million light-years away from Earth in the constellation Hydra, and is one of the closest and brightest spiral galaxies in the sky, visible with only binoculars.By analyzing the gas flowing into the black hole, they inferred its weight as less than 100 times that of the sun. Theresearchers compared the mass of the black hole with its outgoing kinetic power, which they estimated by looking at how bright its surroundings are with infrared and radio waves — the brighter the surroundings, the more kinetic energy jets and winds from the black holes must be slamming them with.The scientists discovered the amount of kinetic energy flowing out from this black hole was perhaps two to five times higher than the Eddington limit for a black hole of this mass.
