Sentences with phrase «radio afterglow»

Not exact matches

If astronomers act quickly, they can turn other instruments toward the point of origin and record a rapidly fading afterglow of x-rays, visible light and radio waves.

As the wave expands and the fire fades, the afterglow changes «color» from x-ray to optical light to radio waves.

Using radio telescopes in Australia and optical telescopes in Hawaii, Keane and his colleagues detected an FRB and linked its fading afterglow to a host galaxy some six billion light - years from Earth.

Instead they found a persistent radio source whose strength varied randomly by a factor of three, often reaching levels that matched the initial brightness of the claimed afterglow.

«Fast radio burst «afterglow» was actually a flickering black hole.»

Last February a team of astronomers reported detecting an afterglow from a mysterious event called a fast radio burst, which would pinpoint the precise position of the burst's origin, a longstanding goal in studies of these mysterious events.

New research by Harvard astronomers Peter Williams and Edo Berger shows that the radio emission believed to be an afterglow actually originated from a distant galaxy's core and was unassociated with the fast radio burst.

They also discovered that a monthlong afterglow followed the event that could be observed with instruments used to detect optical frequencies, x-rays or radio waves.

Their ultraviolet light reached free hydrogen gas in the surrounding regions, interacting with the atoms in a way that left a key signature in the radio spectrum from the afterglow of the Big Bang.

The researchers used radio telescopes at the South Pole to stare at the cosmic microwave background radiation — a faint afterglow left over from the big bang that permeates the universe.

«Sure enough, the afterglow turned out to be brighter in the X-ray wavelengths, just as it was in the radio.»

First limits on the very - high energy gamma - ray afterglow emission of a fast radio burst.

After the gamma - ray signal disappears, these GRBs exhibit «afterglows» of x-rays, visible light, and radio waves.

However, X-ray, optical and radio emission continues in an «afterglow.»

While the burst's afterglow showed a steady decline in brightness at both optical and X-ray wavelengths, that was not the case at radio wavelengths.

The X-ray observations disfavor simple top - hat jets and support the scenario where both the X-ray and radio emissions are the afterglow of an outflow or structured jet.
