In 2007, astronomers discovered some mysterious signals, called high-speed radio bursts (FRB), a phenomenon they cannot yet explain. According to EarthSky, these bursts are short but strong. Although it lasts 0.001 seconds, the energy it radiates in that millisecond is stronger than that released by the Sun in three days. In April 2020, high-speed radio was repeated three times, once in January, after July and November. Currently, two scientific teams are in charge of the mission of studying the sources of the FRB. Here is what has been discovered so far.
Scientists are bringing a detailed study of the nearest known Fast Radio Burst
An unusual aspect of these FRBs is that most of them cycle rhythmically over and over again, as if waking up from a deep sleep in space exactly on schedule to give us an insight into its possibilities. The two teams nominated for the FRB study used dozens of low-frequency array detections (LOFAR) and a Canadian hydrogen intensity mapping experiment (CHIME) to examine the wavelength range of radio waves produced from its source. Ziggy Pleunis, a physicist at McGill University in Canada, said in a statement that the new research points to the fact that the area around the burst source must be transparent for low-frequency emission.
This differs from some theories that suggest that all low-frequency emissions would be absorbed immediately and could never be detected. In addition, they found that longer wavelengths took longer to penetrate Earth detectors than shorter waves, about three days to be precise. This delay excludes all explanations that were previously limited to periodic activities and thus brings scientists closer to understanding the origins of the FRB.
With this new clue, scientists hope to discover more secrets of this mysterious phenomenon. Their eyes are particularly focused on the theory established in the first paper that suggested that the FRB source would come from an interaction between a magnetic superdense stellar corpse called a magnetar and large accompanying stars in space at least 10 times the mass of our sun. More observations about FRB20180916B will determine the real reality.
