NASA's Hubble Space Telescope of a pair of short gamma-ray bursts neutron star or a black hole with the other two super-dense neutron star and has obtained strong evidence that the merger triggered by small double.
Conclusive evidence obtained by near infrared observations of the Hubble short gamma-ray bursts (GRB) appeared later. GRB observed in short-term post-merger brings together kilonova a new type of explosion.
The left shows the galaxy from the place of GRB 130603B gamma-ray bursts. J112848.22 called SDS + 170418.5 4 billion light-years away in the galaxy catalog. Dated June 13, 2013 at the top right of the Hubble Wide Field Camera 3 image shows the near-infrared light shine from the gamma-ray burst sources. gradbeteckningar In the following, dated July 3 shows that the brightness of the image decreases.

1000 times brighter than a white dwarf nova causing a kilonov to the explosion. Nevertheless, the observed brightness of the supernova explosion of a huge star such an explosion 1/100 to 1/10 is up.
Gamma-ray bursts scattered in random directions in space are flashes of high-energy radiation. Some of which may be the majority of short-term burst some time but it appears a few seconds a few hours throughout the day and create a faint redness under near-infrared gradbeteckningar light.
Astronomers have trouble seeing this pale GrB in distant galaxies. Short term GrB is a mystery. However for the most popular theory is an intensive energy transfer gradbeteckningar in two compact object space. But so far failed to produce conclusive evidence thereof.
Nial Tanvir of the University of Leicester England under near infrared light, led a research team used Hubble to examine the short-term boom. Observations revealed faint light seen after an explosion gradbeteckningar kilonov.
"This observation solves the mystery of the origin of the short gamma-ray bursts. Where in many astronomers in our work with a group of long gamma-ray bursts (longer than two seconds) has provided an extremely massive evidence produced before the collapse gradbeteckningar of the star. However, the evidence was weak for that matter formed by the combination of intensive. We obtained evidence seem to support both scenarios, "says Tanvir.
Astrophysicists short of a spiral trajectory followed by super-dense gradbeteckningar neutron star in a binary system estimates gradbeteckningar that couples create GrB. Space-time radiation of the system file is spreading like a fabric with small fluctuations. The energy emitted in the form of waves causes the two bodies orbiting very close together. With the merger of the two bodies milliseconds gradbeteckningar permanently out of high radioactive substances. This material is heated and expands a minor explosion. This powerful explosion kilonov visible and near-infrared radiation emitted by the sun emits every few years-seconds. If that's a kilonov takes about a week.
The study team from the University of Berkeley and Lawrence Berkeley National Laboratory Jennifer Barnes and Daniel Kasen made new calculations to determine how it should appear in the kilonova. Hot plasma for a few days while the radiation in the near-infrared kilonov predicted that also should act to prevent the visible light.
NASA's Swift Space Telescope 3 about 4 billion light-years away in a galaxy called GRB 130603B extremely bright gamma-ray burst was recorded in June. So I have come opportunities expected. After the first burst of gamma rays seen in tenths of seconds until the next kilonov to shine while it was about 100 billion times brighter.
Short term model sequence which has the gamma-ray bursts. 1 system consists of two neutron stars orbiting close to each other and follow the spiral trajectory. Space-over time, due to the angular momentum, creating small fluctuations. 2. throw radioactive material into space in milliseconds with the merger of the two bodies. Goals of this article expands and heats up. With the observed gamma-ray burst lasts up to one tenth of a second in the glare of income and kilonov more than 100 billion times brighter conditions. 3. The body emits visible light in the form of infrared light while is to shoot the ball. 4. The environment that surrounds the black hole formed in the debris disk center. (NASA, ESA, and A.

"We could have used the Hubble Barn and bowl's theory to the test with the help of near-infrared light," says Tanvir. Calculations of the first explosion increases
