Sentences with phrase «core of the radio galaxy»

Not exact matches

Then in 1999, astrophysicists detected a steady buzz of x-rays flowing from an object called Sagittarius A *, a radio beacon at the galaxy's core — additional evidence for a black hole.

The black hole drives enormous outflows of plasma from the galaxy's core which produce prodigious amounts of radio emission.

They found that about 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores and the remaining 37 percent comes from galaxies that are rapidly forming stars.

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) of radio telescopes have discovered a cloud of gas apparently being struck by a jet of ultrafast particles powered by the energy of a supermassive black hole at the core of a galaxy 450 million light - years away.

The radio emission comes from the core AND from very large regions on either side of the optical part of the galaxy called «radio lobes».

Astronomers using the National Science Foundation's Very Long Baseline Array of radio telescopes have discovered a cloud of gas apparently being struck by a jet of ultrafast particles powered by the energy of a supermassive black hole at the core of a galaxy 450 million light - years away.

New radio images of galaxies with bright quasar cores show that, though the galaxies appear normal in visible - light images, their gas has been disrupted by encounters with other galaxies.

The «active» part of the galaxy is the supermassive black hole in its core, which spews out strong jets of energetic particles that produce enormous lobes of radio emission.

Astronomer Vera Cooper Rubin found over decades of radio observations that the rotational velocity of clouds of ionized hydrogen (HII regions) in spiral galaxies like the Milky Way was not decreasing at increasing distance from their galactic cores, like the velocity of the planets around the Sun.
