Fast Radio Burst Pinned Down to Giant Stellar Nursery

by Ken Croswell

A young neutron star is probably the source of a repeating signal previously tracked to a dwarf galaxy 2.4 billion light-years away.

If this true it means that the dynamics of galaxies are not on average as similar as was expected.
It could be a statistical outlier of course, doing odd things because of gravity interactions with other nearby galaxies.

How does this effect average galaxy dynamics? What were we expecting?

The linked article suggests this may be a galaxy with very much greater production of new stars than is typical.
One example of such a galaxy probably doesn't affect much what can be expected of looking at galaxies generally though.

Radar; Fast Radio Bursts carry with them the chirp necessary for re-compression to raise the echo above galactic noise.. Select from an inventory of FRBs to match to the distance of local stellar systems so that an echo will occur at a convenient time. An accurate time slot means that a radio telescope can be re-allocated for a short time to pick up the echo.

Do you have a publication as reference discussing this?

I have been promoting the passive inter stellar concept.
Jason Hessels, associate professor at the University of Amsterdam likes the idea but has serious doubts about getting useful signal to noise so I have addressed this difficulty. A target stellar system will comprise many reflection/regereration sources, and creates its own matched filter. If necessary multiple radiotelescopes could be borrowed briefly from SETI for the interval of uncertainty when the reflected FRB is anticipated.

Does this count? Requires a reference to Euclid because the known lengths and angles switch.

Scattered signals on Earth have nothing to do with the claims from above.
