Fast Radio Bursts (FRBs), are very strong radio pulses and it flashes for the very short duration like a millisecond. Well, the origin of this strong extragalactic radio flashes is still known. But there is a strange thing about this radio pulses. During a study, the scientists had found that one source in the sky was sending out repeated flashes. Then they are investigating the flashes coming from that particular spot. It is now said that the source is a dense stellar core known as a neutron star which is located near a very powerful magnetic field, a place like a massive black hole. But still, the mystery is there as it just an assumption. Some more possibilities show that the reason behind this high-power FRBs are dying of black holes or may be collisions of a powerful neutron star. The details were reported at the 231st meeting of American Astronomical Society.
FRBs can burst high energy during its millisecond flashing duration which is more than the energy produced by the sun in hours, days or even weeks. As per the data, these FRBs were first detected in 2007. While investigating database from the Parkes Radio Telescope in Australia, the researchers discovered this new phenomenon. Actually, they were searching the database to know more about a magnetized neutron star knows as Pulsars, and they found this. However, that time the scientists had only detected more than 20 FRBs. But it was estimated that FRBs might occur more than 10,000 times in an entire day.
In 2012, scientists detected the first FRB which was releasing multiple bursts. That FRB named as FRB 121102. Since 2012, it has been given more than 150 flashes. Previously, a research team had stated that the FRB121102 lies in a star-forming region of a dwarf galaxy which is situated more than three billion light-years away from Earth.
Jason Hessels, an astrophysicist at the University of Amsterdam and co-other of the study, informed it is the only source ever detected repeating fast radio burst source. Now in the new study, the researchers informed about the process of FRBs. The new study has been published in the journal Nature. In the study, the researchers analyzed the data of 16 bursts of FRB 121102 from the Arecibo Observatory in Puerto Rico and the Green Bank Telescope located in West Virginia. They focused on a factor of radio waves called polarization. It shows some interesting fact about the polarization of the radio waves. It tells about the direction of vibration. When the polarization goes by an area covered with the magnetic field, it took a Faraday rotation and twisted at that point. Larger magnetic fields cause greater Faraday rotation. Hessels and his team detected that FRB 121102’s radio bursts were more than 500 times more twisted than other radio bursts came from FRBs. However, the team is now conducting more research to find out the exact point of origin of FRBs.
