Sentences with phrase «light 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.

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.

Dark Matter is thought to exist because of its gravitational effects on stars and galaxies, gravitational lensing (the bending of light rays) around these, and through its imprint on the Cosmic Microwave Background (the afterglow of the Big Bang).

So thirsty are theorists for new insights into black holes and relativistic processes that, with each LIGO detection, observational astronomers have leapt into action to target those enormous patches of sky, hoping to see some afterglow or other emission of electromagnetic radiation — even though by definition the resulting larger black hole should emit no light.
