Sentences with phrase «visible afterglow»

An even more interesting possibility, however, is that x-ray flashers come from explosions in even more distant regions of the universe, where cosmic expansion since the Big Bang would have shifted emitted gamma rays into the x-ray range and intergalactic gas blocks visible afterglow, as none of these x-ray flashes have been observed to have a detectable, visible - light afterglow.

Researchers had never confirmed the basic model, because they always spotted supernovae by their visible afterglow, which lingers after the explosion for several weeks.

Not exact matches

To confirm that finding, the Hubble Space Telescope obtained visible - light images of this galaxy and the burst's afterglow (image, top).

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.

These telescopes, along with Swift's own UV / Optical Telescope and other robotic telescopes alerted by the satellites, monitored the six - week afterglow of visible light following the burst.

The visible - light afterglow was detected at the William Herschel Telescope and its distance was determined with the Gran Telescopio Canarias, both located in the Canary Islands.

The team used the Faint Object Camera and Spectrograph (FOCAS) mounted on the Subaru Telescope to thoroughly study the visible wavelength spectrum (Note 1) of the afterglow of a gamma - ray burst (GRB, Note 2), which is a violent explosion of a massive star.

Visible wavelength spectrum of the afterglow of GRB 130606A at redshift of z = 5.913 (Note 3), when the Universe was a mere one billion years old.

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

Quick follow - up observations undertaken with the 8.2 - m Antu instrument at European Southern Observatory's Very Large Telescope in the Paranal and the 1.5 - meter Danish telescope at La Silla identified a faint, point - like object in visible light that was fading rapidly, the optical counterpart of the gamma - ray burst called the «afterglow» (Pedersen et al, 2000).

«Afterglow» doesn't depend on a visible style as much as some of Rudolph's films; he seems so interested in the story, which he wrote himself, that he doesn't need to impose directorial distance.
