There is suspicion that the source of FRB or Fast Radio Bursts is some kind of magnetar. Some of the FRBs might come outside the milky way. And that thing makes them interesting. On ScitechDaily.com is written like this:
"Observations with the Keck 10m optical telescope reveal that FRB 20201124A resides in a low-density interim region of a Milky Way-like galaxy. This environment is inconsistent with a young magnetar engine formed during an extreme explosion of a massive star that resulted in a long gamma-ray burst or superluminous supernova".(ScitechDaily.com/Dynamically Evolving Environment Discovered Around a Repeating Fast Radio Burst Source).
So researchers investigated one of the most often repeated sources of FRBs by using FAST (Five-hundred-meter Aperture Spherical radio Telescope) In China and 10 m. Keck-telescope in Hawaii. Then the data of those systems are connected to one entirety. There is a link to that article below this text. Or here:

There is the possibility that there are multiple reasons. That is causing those mysterious high-energy radio bursts.
There is always a possibility that the FRBs are forming when the energy bursts from extremely fast rotating magnetars traveling through the interstellar nebula whose energy level is extremely high. And that nebula pumps energy to that radio burst. In some other theories, the FRB is formed when a radio burst travels through the shockwave of the supernova explosion.
But in the most interesting theories, the rotation speed of magnetar locates outside galaxies causes it sometimes sends extraordinarily powerful radiation bursts. And in the most interesting version of that theory goes like this. The magnetar rotates in the WARP bubble or its rotation causes the electromagnetic cavitation bubble.
When that bubble pushes the quantum fields away from its surface the magnetar will put in electromagnetic low-pressure. In that bubble, the rotation speed virtually crosses the speed of light. The electromagnetic wall isolates magnetar from its environment.
And that environment is at a lower energy level than galaxies are. Also, the density of the material is lower than in galaxies' material disks. That thing causes a situation where the magnetar will not get material or energy. Or the energy level of magnetar will travel away faster than energy. And impacting material can replace it. All energy that a neutron star sends forms when material impacts its core.
So that causes the bubble around the magnetar will collapse. And then the magnetar's surface scratches the quantum field. Maybe the source of FRB is in electrons that this neutron star captured. When those electrons fall on the magnetar. That causes a very powerful reaction.
Or other material hits its core. That causes an extremely high-energy reaction. Where fast rotating magnetar sends radiation in the form of FRB.
But that thing is speculation. In that case, the birth of FRB is in a magnetar that rotates faster than magnetars usually. And if that thing hits something the reaction would be stronger, than it usually is.
