The reporter learned from the Chinese Academy of Sciences: China Tianyan has a new discovery again! China Eye Fast Fast Express Radio -Storm priority and major project science research team used FAST operating the National Observatory of the Chinese Academy of Sciences to carry out deep observations of FRB 20201124A. It obtained the largest fast radio violent polarization observation sample to date. For the first time The magnetic field changes in the surrounding environment of only one astronomical unit (that is, the distance from the sun to the earth) are only a key step in determining the engine mechanism of the fast radio violence center. The result was published in the international academic journal "Nature" magazine on September 21, 2022, 2022.
(Fast radio storm and host galaxy art imagination. The world's largest single -caliber radio telescope China Sky Eye (bottom left) and the highest single -caliber optical telescopic telescope (upper right) with the highest space resolution to undertake this study observation.
Fast Radio Burst (FRB) is an occasional radio explosion incident in the universe. Within a few milliseconds, the energy of the radio power bands released by them is equivalent to the total of the world's current total power generation of tens of billions of years, but the physical origin of rapid radio storms is still unclear, and the center mechanism is unknown.
The research team used Fast to conduct long -term monitoring of FRB20201124A outside the galaxy. It was measured in a total of 82 hours of 54 days of observation that 1863 explosive pulse signals from this fast radio storm were measured. Based on the largest fast radio violence polarization observation samples so far, the research team has achieved several important discoveries, all of which are the first internationally.
It is reported that nearly a hundred people in China ’s FAST FAST FAST Fast Express Radiovascular Storm are closely cooperating with the scientific research team of major projects, looking forward to finding direct observation evidence to determine the core physical process and energy mechanism of fast radio violence, guide international multi -wave bands to jointly observe, and reveal fast radio violence as soon as possible Physical origin.
