A curious correlation between the mass of a galaxy's central black hole and the velocity of stars in a vast, roughly spherical structure known as its bulge has puzzled astronomers for years. Astronomers have now identified a new type of black-hole-driven outflow that appears to be both powerful enough and common enough to explain this link.
