Event Horizon Telescope observes a black hole-powered jet
One year ago, the Event Horizon Telescope (EHT) Collaboration published the first image of a black hole in the nearby radio galaxy M87. The collaboration has now extracted additional new information from the EHT data on the distant quasar 3C 279, allowing them to image in the finest detail ever a relativistic jet that is believed to originate from the vicinity of a supermassive black hole. New analyses, led by Jae-Young Kim from the Max Planck Institute for Radio Astronomy in Bonn, Germany, enabled the collaboration to trace the jet back to its launch point, close to where violently variable radiation from across the electromagnetic spectrum arises. The results are published in the April 2020 issue of Astronomy & Astrophysics. The EHT collaboration is continuing to extract information from the groundbreaking data collected in its April 2017 global campaign. One target of the observations was a galaxy 5 billion light years...
