An energetic explosion in the cosmos has been discovered via its not-so-energetic afterglow.
2-meter telescope in Southern California spotted a visible-light flash that brightened dramatically within about an hour, fitting the profile of a burst's afterglow.
K, said that just four minutes after it received Swift's trigger, the telescope found the burst's visible afterglow and began making thousands of measurements.
Over the following 10 minutes, RINGO2 collected 5,600 photographs of the burst afterglow while the properties of the magnetic field were still encoded in its captured light.
Nearly all the afterglows that astronomers have detected come from gamma-ray bursts that arose in galaxies that lie 2 billion to 8 billion light-years away.
Because afterglows fade rapidly, we really had to scramble when we received the alert," Perley said.
Swift autonomously locked onto the location, and the satellite focused its onboard telescopes in less than a minute to capture the burst afterglow.
Previous X-ray images had captured a burst's afterglow, but not the burst itself, notes Swift principal investigator Neil Gehrels of NASA's Goddard Space Flight Center in Greenbelt, Md.
22 burst and its X-ray afterglow, first detected by the Italian satellite BeppoSAX, was also examined by NASA's Chandra X-ray Observatory.
Loeb estimates that less than 1 percent of all afterglows are magnified by a lens.
If the new models are correct, afterglows should be visible much more often than the bursts themselves.
My research lead to a discovery on how near-infrared light waves can increase a woman's sexual response and ultimately to the development of AfterGlow, the first laser-based sex toy, and responses from users have shown the technology to be effective.
Born from results generated from my work using light technology to treat medical disorders of the vagina and bladder, Afterglow aims to reach a consumer base of elegant, modern women and couples, and sets a new standard in adult play for years to come.
Within an hour, astronomers began training ground-based telescopes on the same patch of sky to study the burst's infrared afterglow.
Detecting the afterglow of a distant gamma-ray burst isn't as daunting a task as it might at first appear.
