"Hubble's observations suggest that this particular burst was sitting in a very dense environment, right in the middle of a bright galaxy 5 billion light years away", study author Andrew Levan, a scientist with the Institute for Mathematics, Astrophysics and Particle Physics Department of Astrophysics at Radboud University in the Netherlands, said in a news release. Most radiation/light in the astronomical event is released as Gamma rays.
In step with the researchers, the form of the seen spectrum of afterglow mild used to be indicative of an emission direction of known as inverse Compton emission, which they mentioned is recurrently produced in gamma-ray bursts.
"MAGIC, the TeV photon detector in La Palma, Spain, opened up a new window for research on gamma-ray bursts", Dr. Kouveliotou said.
The researchers, including those from George Washington University in the USA, detected a burst on January 14 labeled GRB 190114C which led to a collaborative effort to observe the radiation coming from the source using more than 20 observatories and instruments around the world. When they come into contact with our atmosphere, gamma rays trigger a cascade of particles that in turn produces the phenomenon known as Cherenkov light, which can be detected by a specially equipped telescopes.More news: Salah, Robertson out for Liverpool trip to Crystal Palace
Woudt and Diretse were part of a team responsible for tracking the emission of radio waves in the afterglow of GRB 190114C.
The GRB 190114C explosion was detected on January 14 by researchers at George Washington University in the US. This collaborative effort allowed researchers to gather the most information ever collected about a GRB, capturing the evolution of the GRB afterglow emission across 17 orders of magnitude in energy.
The new results were published on November 20 in the journal Nature.
Scientists had long suspected that this scattering was one way gamma-ray bursts could produce so much ultra-high-energy light in the afterglow phase.More news: Pep Guardiola's agent hints at return to Bayern Munich
"We have been looking for [such an event with high-energy particles] for longer than 20 years", Razmik Mirzoyan, the spokesperson for the Major Atmospheric Gamma Imaging Cherenkov Telescopes (MAGIC) collaboration and co-author on the new study, told Live science.
While we had anticipated the detection of gamma-ray bursts at these high energies, the discovery that they were still around many hours after the initial burst came as a great surprise.
The energy of these bursts is measured in electron volts (eV), where one electron volt is the amount of energy gained by a single electron when accelerated by one volt. Gamma rays are like particles of visible light, but each of these high-energy rays carries as much as 100 billion times more energy. European astronomers were provided observing time with the NASA/ESA Hubble Space Telescope to observe the gamma-ray burst, to study its environment and find out how this extreme emission is produced . If this jet is pointing towards Earth, we can see it as a bright gamma-ray burst, which typically lasts no more than a minute or two.More news: Manila-bound Philippine Airlines flight makes emergency landing in Los Angeles
HESS observed last year's GRB's afterglow ten hours after the burst occurred, a duration that has never been seen before, in high energies that have never been observed before. The burst occurred in a galaxy situated around five billion light years away. As we enter an era of multi-messenger astronomy, future GRBs are likely to be studied by Cherenkov telescopes along with observations by gravitational wave observatories and neutrino detectors.
