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 …

An enormous X-ray jet extends at least a million light-years from the quasar. Image is 60 arcseconds on a side. RA 11h 30m 7.10s Dec −14° 49' 27" in Crater. Observation date: May …

2020年10月14日 · “It could provide new insight into the physics of these jets.” An important implication of their work is that to produce powerful jets a quasar must have a bright black hole …

2024年12月5日 · The Hubble coronograph allowed astronomers to look eight times closer to the black hole than ever before. Scientists got rare insight into the quasar’s 300,000-light-year …

2025年2月13日 · Funneling all that material causes some black holes to unleash an extraordinary amount of energy that scientists believe fuel the formation of a quasar — the brightest known …

2024年12月6日 · J1601+3102 is an extremely radio-wave quasar with a redshift of 4.9, discovered in 2022. It has a radio emission at 69 mJy, a bolometric luminosity of about 26 …

5 天之前 · One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by …

2007年3月13日 · 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 …

2025年1月13日 · These quasar jets are most often found in large elliptical galaxies, thought to have formed in galaxy mergers. But a recent discovery mysteriously shows a quasar jet in a …

2025年2月6日 · From decades of astronomical observations scientists know that most galaxies contain massive black holes at their centers. The gas and dust falling into these black holes …
