Relativistic jets are beams of ionised matter accelerated close to the speed of light. Most have been observationally associated with central black holes of some active galaxies, radio galaxies or quasars, and also by galactic stellar black holes, neutron stars or pulsars.
In the new study the team chose to investigate the behavior of quasars that do have jets. They found a correlation between how bright the different quasars are in X-rays and ultraviolet light that is remarkably similar to that found for quasars without jets.
An international group of scientists has published new observations of the first quasar ever identified, known as 3C 273 and located in the Virgo constellation, that show the innermost, deepest parts of the quasar’s prominent plasma jet.

The image of the 3C 273 jet gives scientists the very first view of the innermost part of the jet in a quasar, where the collimation or narrowing of the beam occurs. The team further found that the angle of the plasma stream flowing away from the black hole is tightened up over a very long distance.
Stretching across about one million light-years -- far longer than the diameter of the Milky Way galaxy -- the jet comes from the center of a quasar so distant that its light has been traveling towards us for 8.2 billion years, almost two-thirds of the age of the universe.
An international team of scientists has observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world.
An international team of scientists has observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
An international group of scientists has published new observations of the first quasar ever identified — the one labeled 3C 273, located in the Virgo constellation – that show the innermost, most profound parts of the quasar’s main plasma jet.
