Sentences with phrase «radio wave emissions»

Positive detections of radio wave emissions due to Venusian lightning have been reported (Ksanfomaliti et al. 1979; Taylor et al. 1979; Russell et al. 2007).

Mini-jets of material ejected from a central supermassive black hole appear to be the culprits behind faint radio wave emissions in «radio - quiet» quasars.

Her team studied infrared and radio wave emissions from disks in several star - forming clusters with well - known ages.

Mooley and colleagues suggest that the rise in radio wave emissions could be explained if the jet slammed into a shell of neutron - rich material kicked out in the neutron star crash, transferring most of its energy to that debris and smothering the jet.

Radio wave emissions continued to brighten for at least 93 days, and are still visible now, the team found.

Not exact matches

The X-ray data show hot gas and the radio data show emission from electrons that have been accelerated to high energies by the nova shock wave.

And just as we can regard radio emissions as waves and not as photons because of their long wavelength, the gravitational waves that we detected were of sufficiently long wavelength that we could indeed regard them as waves.

Previous studies had measured the amount of radio emission coming from the distant Universe, but had not been capable of attributing all the radio waves to specific objects.

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.

In the same way large antennas on rooftops direct emission of classical radio waves for cellular and satellite transmissions, the nano - antenna efficiently directed the single photons emitted from the nanocrystals into a well - defined direction in space.

Three images, left to right, of the same thundercloud depict a less - than -10-milliseconds-long sequence of events: (left) formation within the cloud of a small channel, or «leader,» of electrical conductivity (yellow line) with weak emission of radio signals (ripples), to (middle) a burst of both dark lightning (pink) and radio waves (larger ripples), to (right) a discharge of bright lightning and more radio waves.

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.

Observations of the shock between this pair of clusters showed that the radio emission was connected to the galaxy's jet, so clearly the electrons must have been initially accelerated by the black hole and then reaccelerated by the shock waves.

Thomas Dame at the Harvard - Smithsonian Center for Astrophysics in Massachusetts and his colleagues got around this by looking at a jet of radio waves that can outshine any emissions from that mess of stars.

The first is the FIELDS experiment which will examine the different fields in the corona, including the Sun's magnetic field, electric fields, waves, plasma density, electron temperature, density fluctuations and radio emissions.

Another of his recent work, on how to strategically point telescopes to find electromagnetic counterparts to gravitational wave sources, was adapted for observations by the Very Large Array radio telescope in New Mexico, which successfully observed radio emission from the merger.

If viewed from an angle away (off - axis) from the center of the jet, the long - term emission of X-rays and radio waves would be getting weaker.

While gamma rays arrive first in the Solar System and overshine lower energy emissions, x-rays, visible and infrared light, and radio waves associated with the supernova are eventually perceived as well (more images).

Kasliwal's colleague, theorist Ehud Nakar of Tel Aviv University, pointed out that the absence of X-ray and radio emissions fit a model in which the ejected material from the merged neutron stars produced a blast wave that interacts with the interstellar medium but with a time lag.

Galaxies and quasars, and the «jets» of subatomic particles ejected at great speeds by some of these objects, have definite patterns of polarized emission of light and radio waves.

«telegraph» means any appliance, instrument, material or apparatus used or capable of use for transmission or reception of signs, signals, writing, images and sounds or intelligence of any nature by wire, visual or other electro - magnetic emissions, Radio waves or Hertzian waves, galvanic, electric or magnetic means.»
