A team of astronomers observed the narrowing of the jet of the quasar 3C 273

(ORDO NEWS) — An international team of scientists using a network of radio telescopes around the world for the first time observed the narrowing of a quasar jet.

The results of the study show that the narrowing of the jet does not depend on the level of activity of the galaxy that launched it.

Near the center of every galaxy is a supermassive black hole. In some cases, a huge amount of energy is released by the gas falling towards the black hole, creating a phenomenon known as a quasar.

Quasars emit narrow collimated jets of matter at speeds close to the speed of light. However, how and where quasar jets collimate has long been a mystery.

An international team of researchers led by Hiroki Okino, a PhD student at the University of Tokyo, has obtained the highest angular resolution image to date, showing the deepest part of the jet in the bright quasar 3C 273.
