FRBs: A mysterious signal moving in our galaxy, the Milky Way, emanated from the universe’s most powerful magnet?


In April last year, two radio telescopes detected fast radio bursts close to Earth for the first time. It was 30 thousand light years away from us. It was gone in the blink of an eye. Prior to this, FRBs had not been detected inside our Galaxy. They passed billions of light years away, so they were not easy to study. Now it is believed that the source of this FRB can also be traced.

It was detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and the Survey for Transient Astronomical Radio Emission (STARE2). Kiyoshi Masui, assistant professor of physics at the Massachusetts Institute of Technology, says that they come from a source that will be only a few hundred kilometers wide. It is likely that it comes from a neutron star because both are very small and full of energy.

Where did FRB come from?
Based on data from other telescopes, it is believed that these FRBs must have come from a magnetar. These are such neutron stars that are formed from a supernova and their magnetic field is 5000 trillion times more powerful than Earth. Due to this they are considered to be the most powerful magnets in the universe.

Such a possibility is being expressed more because their origin is from the Vulpecula constellation and there is also a galactic magnetar SGR 1935 + 2154. During this time the X-ray burst emanating from it was also detected.

Finding the Source Important, Difficult
It is also understandable what is happening in the Galaxy from where the FRBs are coming. The amount of energy the Sun emits in a year, FRBs do it in a thousandth of an instant. In such a situation, the discovery that will be done about them will help in understanding more about them. The problem is that these can only be observed for a few milliseconds and when they will happen is not known. This makes it difficult to ascertain their source or cause.
