Sentences with phrase «radio jets»
"Radio jets" refers to powerful streams of energy and matter that shoot out from the centers of some galaxies. These jets emit radio waves and travel across vast distances at close to the speed of light. They are created by supermassive black holes, which release immense amounts of energy as they consume nearby material. The study of radio jets helps scientists understand the physics of black holes and the processes happening in galaxies. Full definition
Figure 1 Composite image showing how powerful radio jets from the supermassive black hole at the center of a galaxy in the Phoenix Cluster inflated huge «bubbles» in the hot, ionized gas surrounding the galaxy (the cavities inside the blue region imaged by NASA's Chandra X-ray observatory).

Powerful radio jets from the supermassive black hole at the center of the galaxy are creating giant radio bubbles (blue) in the ionized gas surrounding the galaxy.
Drs. Alan Roy and James Ulvestad of the National Radio Astronomy Observatory, together with Drs. Edward Colbert and Andrew Wilson of the Space Telescope Science Institute and the University of Maryland, used the VLBA to image a light - year - sized radio jet in NGC 4151, a relatively nearby spiral galaxy.
This result helps astronomers understand the workings of the cosmic «thermostat» that controls the launching of radio jets from the supermassive black hole.
Neutron stars have two large radio jets that come out of each of the star's magnetic poles.
This large - scale radio jet is nearly coincident with a complex of gas clouds imaged at optical wavelengths with the Hubble Space Telescope.
The radio images of NGC 4151 reveal a chain of knots several light years in length, separated by a few light months, which then appear to make a fairly sharp turn — about 55 degrees — to merge with a previously known straight radio jet about 800 light - years in length.
The southwestern (lower right) region of this image contains the 2.6 - light - year radio jet seen at higher resolution in the 6 - cm image, curving by ~ 55 degrees into the region of more extended radio emission.
Publication information: The paper «A wide and collimated radio jet in 3C84 on the scale of a few hundred gravitational radii» was published in Advance Online Publication (AOP) on the Nature Astronomy website on 02 April 2018.
Messier 108 also contains H1 supershells, shells of expanding gas driven either by bursts of star formation and the resulting supernova explosions, or by infall of gas from outside the galaxy, or possibly by radio jets.
Powerful radio jets from the black hole - which normally suppress star formation - are stimulating the production of cold gas in the galaxy's extended halo of hot gas.
Powerful radio jets from the black hole — which normally suppress star formation — are stimulating the production of cold gas in the galaxy's extended halo of hot gas.
The radio jets that heat the core of the cluster's hot atmosphere also appear to stimulate the production of the cold gas required to sustain the AGN.
The water to the right is at the position where the radio jet bends down wards.
The radio jet is shown in green, and the position of the dust and water are seen in blue.
The radio jets compress clouds of gas along their path and heat up water molecules contained within the clouds until they emit radiation.
But the interaction with the radio jets changes the composition of the gas clouds.
As shown in our additional, composite image, part of the evidence for this heating process comes from the similarity in location between the hydrogen and X-ray emission, both thought to be caused by shocks, and the radio jets.
The radio jet is 2.6 light years long.
