A 'strange signal' is coming from the Milky Way. What's causing it?

Interesting report. Perhaps magnetars are the source of FRBs. This report discusses a magnetar and discloses some properties. https://phys.org/news/2021-06-behavior-magnetar-sgr-j17452900.html Ref - Phase-Resolved Spectroscopy of the Magnetar SGR J1745-2900 Based on Data from the NuSTAR Observatory, 09-June-2021.

My observation. The 9 page arXiv paper link https://arxiv.org/pdf/2106.05070.pdf, Using a model pulsar with 1.4 solar mass and radius 10 km, mean density ~ 6.65E+14 g cm^-3. Rotation period 3.76 s so spin rate at equator ~ 16.7 km/s.


"There never was a good war, or a bad peace."
"The FRB discovered in the Milky Way is now helping astronomers to firm up such theories, and it’s become something of a breakthrough for scientists trying to get to the bottom of what is causing them."

"FRB's can release as much energy in a few thousandths of a second as the sun in 100 years."

Simply amazing. We've detected only 140 of them. Perhaps because they are so far away. we need to be pointed almost exactly where they occurred to detect them. Because one was detected in this galaxy, they may be far more common than expected.

It's amazing to realize that the magnetic field of a magnetar can be a trillion times as strong as the earth's magnetic field - strong enough to strip atoms of their properties and then convert that into such powerful bursts of energy. I'm not sure if I have the proper picture, but it looks like every sub-particle of those stripped atoms is suddenly converted into pure energy after a building-up period - perhaps not unlike an anti-matter/matter collision.
