Team of scientists observes inner structure of quasar jet | News

An international team of scientists has observed the constriction of a quasarjet for the first time using a network of radio telescopes around the world. The results suggest that the jet’s constriction is independent of the activity level of the galaxy that launched it. Almost every galaxy has a supermassive black hole at its center. In some cases, massive amounts of energy are released by gas falling toward the black hole, creating a phenomenon known as a quasar. Quasars emit narrow, collimated beams of material at nearly the speed of light. But how and where quasar jets are collimated has long been a mystery. The team found that the jet flowing out of the quasar narrows over a very long distance. This narrowing part of the jet continues incredibly far, well beyond the region where the black hole’s gravity dominates. The results show that the structure of the jet is similar to that of nearby galaxies with an active core at low brightness. This would indicate that the jet’s collimation is independent of the activity level in the host galaxy, providing an important clue to unraveling the inner workings of jets.
