Fast Radio Burst Pinned Down to Giant Stellar Nursery

In summary, a neutron star is the most likely source of a repeating fast radio burst signal that has been spotted in a different galaxy. This suggests that the dynamics of galaxies are not on average as similar as was expected.

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.

Please reference a publication. Personal speculations are against the forum rules.

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.
 

1. What is a Fast Radio Burst (FRB)?

A Fast Radio Burst (FRB) is a transient, millisecond-duration burst of radio waves that originates from sources outside of our Milky Way galaxy. They are highly energetic events, releasing as much energy in a few milliseconds as the Sun does in a day.

2. What is the significance of pinning down the origin of a FRB to a giant stellar nursery?

The origin of FRBs has been a mystery since their discovery in 2007. Pinning down the location of a FRB to a giant stellar nursery provides valuable information about the source of these bursts and can help us better understand the physics behind these events.

3. How was the giant stellar nursery identified as the source of the FRB?

Using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, astronomers were able to pinpoint the location of a FRB and identify it as coming from a giant stellar nursery. They used a technique called interferometry, which combines multiple telescopes to create a more detailed image, to locate the source of the burst.

4. What can we learn from studying FRBs in giant stellar nurseries?

Studying FRBs in giant stellar nurseries can provide valuable insights into the environments in which these bursts occur. It can also help us understand the nature of the progenitor objects that produce these bursts.

5. Are there any potential applications of this discovery?

Yes, there are potential applications of this discovery. By studying FRBs and their origins, scientists can gain a better understanding of the universe and its evolution. Additionally, the technology used to detect and study FRBs can also have practical applications in communication and navigation systems.
