com/articles/nature25149) The paper , titled "An extreme magneto-ionic environment associated with the fast radio burst source FRB 121102," appeared online Wednesday in the journal Nature.

How Do Fast Radio Bursts Originate?

Because of Earth's off-center location in the Milky Way, she says, the symmetric distribution argues against a burst source associated with our own galaxy unless the bursts originate in a huge halo whose inner diameter is double that of the Milky Way.

Shedding more light on gamma-ray bursts

In his paper Maley mentions three that seem to have come from a gamma-ray burst source in the supernova remnant N49.

We've seen this effect in other fast radio burst sources before, but in this case the effect is 500 times larger than what we've seen at other sources," Hessels said.

Burning bright

But if the burst sources are so far away, then the energy released in a burst is unimaginably high.

Those mysterious cosmic gamma rays

Conversely, if the intensity distribution does not follow the -3/2 power law, the burst sources are not homogeneously distributed.

The burst sources might be more distant that those in the heliocentric model but still closer than the boundary of the galactic disk in the solar neighborhood.

If the burst sources are not galactic disk objects, as now seems likely, we are left with only three possible models.

The mystery that won't go away

The next step will be to try to pin down more precisely where the burst sources are located and to try to find radiation of lower energy that may be emanating from the same sources.
