The use of observations of a new study provides the best appearance from the gamma-ray burst, the most energetic explosion of the heart's magnetic field in the universe. Astronomers from Britain, Slovenia and an international research team in Italy have already caught a glimpse of the high-speed jet infrastructure.
Gamma-ray bursts are the brightest explosions in the universe. Most are thought to be when a massive star's core depleted nuclear fuel is triggered, collapses according to its own weight, and forms a black hole. The black hole then drives the particle drill, passing the collapsing star and exploding to a near-space velocity jet.
On March 8, 2012, NASA's Swift satellite detected a 100-second pulse of gamma rays from the constellation Ursa minor source. The spacecraft immediately forwarded the location of the gamma-ray burst, known as the GRB 120308A, and observed it globally. The world’s largest fully autonomous robotic optical telescope, located at the 2m Liverpool telescope located at the Roque de los Muchachos Observatory in La Palma in the Canary Islands, automatically responded to Swift's notice.
Four minutes later, after receiving a Swift trigger, the telescope discovered a burst of visual afterglow and began to make measurements of thousands, chief researcher Carol Mondale, in charge of the gamma-ray squadron in astrophysics. Institute at Liverpool John Moores University UK. The telescope was fitted with an instrument called RINGO2, which was designed by Mundell's team to discover any preferred direction, called polarization, in the after-glow vibration of the light waves from the explosion.
Mundell's team built RINGO2 to detect the long-term hypothesis of the magnetic field driving and focusing the jet of gamma-ray bursts. The shoebox-sized instrument has an ultra-fast camera for the spinning polarization filter. The energy of the entire spectrum, from radio waves to gamma rays, is when an inkjet slams its surroundings and begins to decelerate. This will result in the formation of an outwardly moving shock wave. At the same time, the reverse shock wave drives back the ejected debris, which also produces bright light.
The theoretical model of gamma-ray burst predicts that light from a reverse impact should exhibit a strong and stable amount of polarized emissions. If the jet has a newly formed black hole around the origin in a structured magnetic field environment, it is considered a "central engine" burst. drive. The previous observational optical persistence detected about 10% polarization, but they did not provide information on how to use this value over time. As a result, they cannot be used to test the competitive spray model.
The rapid orientation of the Liverpool telescope enabled the team to catch an explosion and an initial burst after just four minutes. After 10 minutes, RINGO2 collects a burst of afterglow of the 5600 photo and the nature of the magnetic field is still encoded in its captured light. Observations showed that the initial afterglow was polarized by 28%, setting a maximum value for continuous shooting, and then gradually dropped to 16%, while the angle of polarized light remained unchanged. This supports the large-scale, organized magnetic field connected black holes, rather than the presence of entangled magnetic fields created by the instability of the jet itself.
