First discovered in 2007, fast radio bursts (FRBs) have puzzled scientists for years. In just a few milliseconds, these radio waves manage to discharge more energy than hundreds of millions of suns. The exact origin and cause of FRBs is uncertain.
Mysterious FRBs have been discovered in the arms of spiral galaxies, claims an international group of scientists. According to the findings of their study, which will be published in The Astrophysical Journal, astronomers have traced the locations of five radio pulses that they assume originated in the areas of galaxies where star formation occurs, known as the spiral arms.
The researchers said it was surprise to discover that the fast radio bursts originated in the spiral arms. This detail offers a clue that they must correlate with star formation, said Wen-fai Fong, an assistant professor of physics and astronomy at Northwestern University’s Weinberg College of Arts and Sciences in Illinois and co-author of the study.
Previously, researchers assumed that FRBs could appear as a result of mergers of neutron stars or following explosions of young stars.
The discovery sheds more light on the mystery of FRBs, but at the same time prompts more questions. For example, scientists previously detected them in Magnetar SGR 1935+2154, located in our Milky Way galaxy.
Alexandra Mannings says the more FRBs scientists observe, the more they think different types of bursts have different origins.
