Telescope event horizon was able to build the most detailed image of the relativistic jet, which rises from the core of the distant blazar 3C 279. Such observations allow us to understand the mechanisms of particle acceleration in the jets and their formation. Article published in the journal Astronomy & Astrophysics.
Observations with the EHT, have allowed us to construct detailed maps of the area size of 1700 SmartSlice radii around a black hole with angular resolution of 20 arc microseconds. Form Central elongated structure remained unchanged throughout the observation period, it can be interpreted as the broad base of the jet or as it is curved part, which may be magnetic reconnection or plasma instability. Small structures that appear in the images may occur due to the rotation of the accretion disk and grinding and falling into the black hole of matter. Two internal parts of the jet move with apparent velocities of 15 and 20 (where C is the speed of light), which increasingly supports the scenario of propagating shock waves or instabilities in curved rotating jet plasmas and may also explain the intense flux of gamma radiation.
Unfortunately, the observation campaign EHT, which was scheduled in March and April 2020, was cancelled in connection with the coronavirus pandemic, it is expected that by the spring of 2021 in the project will include three Observatory.
