Astronomers Pinpoint Location of Mysterious Cosmic Radio Bursts

New submitter Netdoctor writes: Fast Radio Bursts (FRB) are massively powerful short-lived radio bursts from far-away sources, and so far a number of theories exist on what generates them. Recently several were detected in the same general location, which adds to the mystery, as any of these pulses would be powerful enough to destroy a source. Since this group of FRBs were detected with single radio telescope dishes, the exact location was difficult to pinpoint. BBC reports here with results from the Very Large Array in New Mexico being trained on the source. From the report: “Outlining their work at a major conference, astronomers say they have now traced the source of one of these bursts to a different galaxy. Dr Chatterjee, from Cornell University, New York, and colleagues used a multi-antenna radio telescope called the Very Large Array (VLA), which had sufficient resolution to precisely determine the location of a flash known as FRB 121102. In 83 hours of observing time over six months in 2016, the VLA detected nine bursts from FRB 121102. In addition to detecting the bright bursts from FRB 121102, the team’s observations also revealed an ongoing, persistent source of weaker radio emission in the same region. The flashes and the persistent source must be within 100 light-years of each other, and scientists think they are likely to be either the same object or physically associated with one another. He said some features of the radio source resembled those associated with large black holes. But he said these were typically found only in large galaxies.”
