A team of researchers reached a new milestone by recording the first set of polarized radio waves from a distant explosion classified as a gamma ray burst GRB 190114C. It is believed that the cosmic field can flow through the jets, which contributes to the formation of gamma-ray bursts and provides structural support.
The researchers used an unusual method to observe the spectacular phenomenon. Magnetic jets were seen in linearly polarized light, which is quite sensitive to the size and intensity of the magnetic field fragments, as larger fields produce a greater amount of polarized light.
An intense flash of gamma rays activated the Swift satellite, which is operated by NASA in January 2019. Data obtained from the satellite inferred that the stream came from the constellation of Fornax.
Polarized gamma ray burst radar signals first recorded by astronomers
Taking advantage of the power of the Atacama Large Millimeter / Submillimeter Array (also known as ALMA), which is found in Chile, researchers have begun to search the sky in an attempt to track the radio waves generated by the explosion. The high-intensity event occurred almost 4.5 billion years ago in a galaxy located 7 billion light-years away.
The results were quite fascinating as the team was able to track a 0.8% polarization signal, which infers that the magnetic field fragments can be as large as our solar system. During the next stage of the study, the scientist will compare current information with data obtained from X-ray and visible light telescopes.
The low frequency data provided by ALMA proved that what the researchers observed was actually a gamma ray overflow and not an interaction between the jets and the environment. Magnetic fields are indescribable and notorious for the difficulty of tracking them. The fact that the team has been able to locate them is a great achievement, and the new information has already aroused the interest of the scientific community. The results were published in a scientific journal.
