More FRB News

[John Clark]

Yesterday the journal Nature reported the detection on May 23 of the most distant Fast Radio Burst ever discovered, it came from a massive galaxy 7.9 billion light years away breaking the previous record set just last week of 4 billion light years:

A fast radio burst localized to a massive galaxy

And last Friday a Russian observatory reported seeing 9 new FRB's at 111MHz ,  and one of them was only the third FRB ever found that repeated:

Search for Fast Radio Burst at the frequency 111 MHz

Now that we know what to look for we're seeing Fast Radio Bursts everywhere, in old galaxies much larger than ours, in young galaxies much smaller than ours, and in galaxies that look very much like ours.

I looked this up on wikipedia

to see what in general is written. I suspect these have primarily to do with electromagnetism, or at least these seem to be the minimal explanation. It is possible this is a process involving the collapse of magnetospheres around neutron stars. As to what might do this is uncertain. The ultradense material in the center of a neutron star might be in a color-flavor mode locked state that has superconductivity. This phase though might have some instability and rapid changes in the phase of this matter could induce rapid changes in the magnetic field of the neutron star. 

The most exotic proposal is

which I doubt very much. In a sense Hawking radiation is a way that black hole solutions become in a sense more white hole. The Schwarzschild conformal diagram 

is a representation of raising and lowering operators. The black hole is a lowering operator that absorbs a state and the white hole is a raising operator that generates one. However, it seems unlikely a black hole with .1 times the mass of Earth would, as the authors here claim, would suddenly transform into a white hole.
