FRBs can produce more energy in mere milliseconds than the sun does in days.
; B. Saxton, NRAO/AUI/NSF))" that bursts constantly across radio frequencies, making it an ideal target of long-term study. But that's not the only reason the team, led by Reshma Anna-Thomas of West Virginia University, selected FRB 20190520B for its research.
"The real motivating factor was its resemblance with a previously well-studied FRB, FRB 20121102A," Anna-Thomas told Space.com."These two FRBs have an environment that is persistently emitting radio waves, which suggests that the FRB source is young. And FRB 20121102A is known to reside in an extremely magnetized plasma environment. So, we wanted to see if that's the same for FRB 20190520B.
Over the course of 17 months, the team watched FRB 20190520B closely using the Parkes Radio Telescope in Australia and the Robert C. Byrd Green Bank Telescope in the United States. Researchers observed high variability in the FRB's Faraday rotation — a change in the radio waves' polarization, which happens when it passes through magnetic fields. That variability indicated a highly turbulent magnetic environment at the FRB source.
"Using the observed properties, we modeled these variations as due to a wind from a massive companion star, and this conclusion was strengthened by a system in theThe team also considered alternative explanations, including FRB 20190520B passing through waves from a
