A noteworthy jet of quasar 4C + 19.44

Quasars represent galaxies with massive black holes in the nuclei. They create such a huge amount of energy that they exceed the rest of the galactic territory in brightness. Most of the radiation is on the radio waves created by electrons ejected from the nucleus at a speed close to the light.

The fast charged particles are also able to scatter photons of light, raising them along the energy level to the x-ray range. But decades of research have not revealed the exact mechanism of their formation. In powerful quasars it can be seen that dispersion dominates, but in low-power reactors the main role is played by the magnetic field.

Scientists decided to focus on the 350-year-old long stream of the quasar 4C + 19.44, using the multi-wave data from Chandra (X-ray), Spitzer (infrared) and the Hubble telescope (optical), as well as Very Large Massive (radio). The combination of a multiwave view and high spatial resolution helped scientists systematically determine the characteristics of the rays at 10 different nodes along the stream. They found that the magnetic field strength and velocity particles are quite constant along the entire length of the jet, assuming that the scattering process is dominant. But while there is no way to eliminate the influence of magnetic effects. For this process to be activated, its electrons must belong to a separate population from scattering electrons.
