![]() ![]() These telescopes detectors reported an X-ray burst originating from SGR 1935+2154 at the same time as FRB 200428. The research was made possible by the data taken from telescopes around the world, including Canada, the US, and China. However, FRB was incredibly bright-1,000 times brighter than what was announced by CHIME. Further, the STARE2 team also confirmed the data for the discovery of FRB-named FRB 200428. Later, the CHIME telescope team confirmed the FRB from the source patch named SGR 1935+2154, thus making it the first FRB with a known source and from our own galaxy. After the observation from space telescopes, the ground-based-Canadian Hydrogen Intensity Mapping Experiment (CHIME) and the Survey for Transient Astronomical Radio Emission 2 (STARE2) surveyed a patch of sky for potential sources. On April 27, 2020, two space observatories-the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope-detected multiple bursts of x-ray emissions from the backyard of our galaxy. student in the Physics Department at McGill. ![]() "We calculated that such an intense burst coming from another galaxy would be indistinguishable from some fast radio bursts, so this really gives weight to the theory suggesting that magnetars could be behind at least some FRBs," said Pragya Chawla, one of the co-authors on the study and a senior Ph.D. Moreover, the current studies also highlight that at least some of these magnetars can produce powerful radio blasts due to their strong magnetic field. These have emerged as a leading candidate for the mysterious FRBs. Out of all the theories that have been suggested by astronomers so far-on their origin-one that validates is the extragalactic magnetar. The majority of cosmic theories so far suggested that these originate from large stellar remnants. Most promising theory so farĪ fast radio burst lasts only a fraction of seconds and emits high-intensity radio waves, which has the capacity to generate more intense energy than that of the Sun would generate over millions of years. However, he does not rule out the other possible sources completely. In the review paper following the three conclusive studies, renowned astronomer Bing Zhang from the University of Nevada concludes that the magnetars can produce at least some, and maybe all, fast radio bursts. "Moreover, the magnetar theory was not supported by observations of magnetars in our own galaxy as they were found to be far less intense than the energy released by extragalactic FRBs until now." student in McGill's Physics department and one of the co-authors of the new study. "So far, all of the FRBs that telescopes like CHIME has picked up were in other galaxies, which makes them quite hard to study in great detail," said Ziggy Pleunis, a senior Ph.D. The magnetar’s activity was first spotted by the Swift space telescope and later confirmed by multiple powerful radio telescopes.ĬHIME Telescope (Andre Renard/CHIME Collaboration ) While most of the earlier FRBs were found travelling from outside our galaxy, the latest one-detected by a team of 50 members-is said to be from a nearby magnetar named SGR 1935. Now, a series of three independent research studies have confirmed now that a magnetar is the source of a fast radio burst named FRB 200428 detected in April. ![]() The extremely short length and undefined origin had made it impossible to analyse these signals effectively. These astronomical phenomena were first discovered by astronomers in 2007, and since then, these mysterious signals have sparked immense curiosity. FRBs are regarded to be super intense radio waves which last for milliseconds. Detecting the source after 13 yearsĪs per the latest study, the fast radio bursts (FRB) detected in April were the first ones that astronomers spotted to be originating from our home galaxy, Milky Way. Magnetars are a type of neutron stars with the strongest magnetic field in the cosmic world and are formed due to the explosion of a massive star. Some theories even suggested that the signal is coming from a distant alien civilization.īut now, a team of astronomers has finally decoded its source suggesting that the mysterious signal is coming from magnetars within our Milky Way galaxy. The seemingly random flickers was regarded as one of the most mysterious cosmic signals ever recorded by radio telescopes to date. In the last week of April this year, a powerful burst of radio waves passed over Earth, flashing up radio telescopes based in various parts of the globe. ![]()
