A combined image of two images of quasar RX J1131-1231 gravitationallly lensed into four copies by a galaxy
Summary
[edit]
| Description |
English: Multiple images of a distant quasar known as RX J1131-1231 are visible in this combined view from Chandra (pink) and Hubble (red, green, and blue). The Chandra data, along with data from ESA's XMM-Newton, were used to directly measure the spin of the supermassive black hole powering this quasar. Black holes are defined by just two simple characteristics: mass and spin. At a distance of 6 billion light years, this is the most distant black hole where such a measurement has been made, allowing for an important advance in understanding how black holes grow over time. |
