3C 279 (also known as 4C–05.55, NRAO 413, and PKS 1253–05) is an
M87* that resulted in the first image of a black hole.[5]
Observations
- The apparent superluminal motion was detected during observations first made in 1973 in a jet of material departing from the quasar, though it should be understood that this effect is an optical illusion caused by naive estimations of the speed, and no truly superluminal motion is occurring.[6]
- 16 June 2015, the 3C 279 had a large gamma-ray outburst, believed to be caused by the injection of high-speed electrons in the central, high-density region.[7]
- Further observations with the Event Horizon Telescope during April 2017 provided a high level of detail to the radio jet, with a resolution as small as 20 micro-arcseconds. They indicated a bent or rotating jet shaped by shock waves.[8]
