Sentences with phrase «strong radio emission»

Observations with radio and infra - red telescopes show that NGC 5128 swallowed a spiral galaxy probably about five hundred million years ago and the effects of the collision powers the strong radio emission.

As gaseous matter is attracted towards the event horizon by the black hole's gravitational attraction, strong radio emission is produced before the gas disappears.

The strong radio emission was unexpected because brown dwarfs, according to conventional theories, are not supposed to have magnetic fields strong enough to generate the radio emission.

«Many astronomers are surprised at this discovery, because they didn't expect such strong radio emission from this object,» said Shri Kulkarni, a Caltech professor who was on the team that first discovered a brown dwarf in 1995, and advisor to one of the students.

A blazar, a galaxy that kicks out fluctuating X-rays, might also have been responsible, but blazars are easily identified by their strong radio emissions, something not apparent in this source (Nature, DOI: 10.1038 / nature08083).

Not exact matches

At radio frequencies greater than 10 gigahertz the radio emission matched that of the microwave background, but at lower frequencies it was several times stronger.

In earlier observations, emission from two or more faint objects often was blurred or blended into what appeared to be a single, stronger source of radio waves.

By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, Schulze's team found that on average the O III oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars.

We know that for energies of modest to intermediate energy, the culprit or the source of the acceleration appears to be the shock front that surrounds a [an] expanding supernova blast wave; that is to say, we have a star that undergoes a massive cosmic explosion [and] drives a strong shock wave out into the surrounding interstellar medium, and the gas around the shock wave, and all the magnetic fields associated with it are capable of accelerating particles to very high energies; and also incidentally magnifying and amplifying the magnetic field associated with that shock front and giving a lot of x-ray emission and radio emission and so on, and so we've understood that.

These so - called relativistic jets produce strong emission at radio wavelengths.

«The radio emission these students discovered coming from this brown dwarf is 10,000 times stronger than anyone expected,» said Dale Frail, an astronomer at the National Radio Astronomy Observatory (NRAO) in Socorroradio emission these students discovered coming from this brown dwarf is 10,000 times stronger than anyone expected,» said Dale Frail, an astronomer at the National Radio Astronomy Observatory (NRAO) in SocorroRadio Astronomy Observatory (NRAO) in Socorro, NM.

This showed that the brown dwarf's radio emission had risen to a strong peak, then weakened.

The target object of this observation is radio source Sagittarius B2 (Sgr B2), which is an object with strong emission, located at near the center of our galaxy.

For the first time, astronomers pinpointed the location of a fast radio burst (FRB), which is a phenomena where a very strong burst of radio emission occurs.

The surface of the Sun is a strong source of radio emission — and of potential harm, so our 45 - foot telescope in Green Bank, West Virginia monitors the Sun the entire time it is in our sky.

When radio telescopes were first used to make detailed maps of the sky in the 1950s, many strong sources of radio emission seemed to have no counterparts in visible light.

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.

Detection of the spiral's dust in a bi-symmetric structure provides strong evidence of its position deep inside the giant elliptical host while the vast amounts of radio, visual, and x-ray emissions are a result of the energy released by this continuing galactic merger (or «consumption» of a satellite galaxy).
