The matter does emit light, making supermassive black holes some of the brightest objects in the cosmos. However, the fortuitous alignment means it will be difficult to replicate the method for most other black holes.īlack holes don't emit light of their own, but matter swirling around them heats up through collisions and acceleration by magnetic fields. This marks the first measurement of black hole rotation outside the local Universe, and it was only possible because the light from this black hole was magnified by a galaxy lying serendipitously between it and the Milky Way. That likely means it was spun up by a small number of mergers with other black holes rather than a gradual increase from eating smaller amounts of mass. Walton found it was spinning nearly as fast as possible. From four separate images of the same black hole, R.C. ![]() For that reason, most of the data we have on them involves tracking the matter swirling around the black hole rather than the properties of the black hole itself.Īstronomers have now used gravitational magnification to measure the rotation rate of a supermassive black hole in a very distant galaxy. Despite their size and influence, they are also relatively small, making detailed observations a major challenge. Supermassive black holes are powerful engines, pumping matter and energy into their environments. NASA/CXC/Univ of Michigan/R.C.Reis et al Optical: NASA/STScI reader comments 95 with ![]()
