The mystery of FRB:s.

"Scientists at the SETI Institute have advanced the understanding of Fast Radio Bursts (FRBs) through detailed observation of FRB 20220912A with the Allen Telescope Array. Their research, uncovering new properties and behaviors of these cosmic signals, highlights the ATA’s unique role in FRB studies and contributes significantly to the field of astrophysics."

FRBs:s or fast radio bursts are extremely high energy radiation bursts in radio wave frequency. In some models, the high-energy material that releases its energy very fast is the reason for those mysterious radio bursts that remain less than a second. The source of FRBs is mysterious, but sometimes the FRB is connected with magnetars and their super powerful magnetic fields. 

Manetars are low mass nautron stars. That makes their shell rotate their core at extremely high speed. In some models, the shell of magnetars can be over the vacuum. And that thing makes those small neutron stars rotate faster than more massive neutron stars. In neutron stars rotating shell that rotates the core forms the massive generator. 

If there is a small vacuum under the magnetar's shell that allows it to rotate hyperfast. It explains magnetars powerful magnetic field. There is neutron liquid under the magnetar shell, and it's possible. This liquid touches the shell of a magnetar. And it forms the FRB. 

In those cases, there seems to be a connection between FRB and fast X-ray bursts. There is a possibility that a very light neutron star called magnetar sends radiation bursts to some magnesite or iron atoms. And then those iron atoms release their extra energy as radio waves. Those iron bites can be in asteroids that orbit those neutron stars. But many other possibilities can form powerful radio bursts.

In some models, the radio burst from some other neutron star, black hole or magnetar hits some other neutron star. In that case, the extremely powerful gamma, X- or radio wave hits the magnetars or neutron stars. And that thing is the launcher for FRB. 

In some other models the radiation from pulsar traps iron into the radiation beams. When that radio wave hits those iron- or some other metal bites it raises that metal's energy level. And then sooner or later those hyperenergy elements fall to the neutron star, or their energy level rises high enough that they send radiation burst. So in that model. Material that has extraordinarily high energy levels impacts neutron stars. And that thing forms extraordinary high-energy waves.
