Fast Radio Burst Pinned Down to Giant Stellar Nursery

Click For Summary

Discussion Overview

The discussion centers around the implications of a Fast Radio Burst (FRB) linked to a young neutron star in a distant dwarf galaxy, exploring its potential effects on our understanding of galaxy dynamics and the nature of FRBs.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants suggest that if the FRB is indeed from a young neutron star, it could indicate that galaxy dynamics are more varied than previously thought, potentially due to gravitational interactions with nearby galaxies.
  • Others propose that the galaxy in question may have a significantly higher rate of new star production than typical galaxies, though one example may not significantly alter general expectations about galaxy behavior.
  • One participant discusses the concept of using FRBs for radar-like applications, suggesting that the chirp of FRBs could be utilized to enhance signal detection above galactic noise.
  • Another participant expresses skepticism about the feasibility of obtaining useful signals from passive interstellar concepts, despite some support from an academic figure.
  • Several participants request references to publications to support claims made, emphasizing adherence to forum rules against personal speculation.
  • A participant asserts that scattered signals on Earth are unrelated to the claims being discussed, indicating a potential divergence in the conversation's focus.

Areas of Agreement / Disagreement

Participants express a range of views on the implications of the FRB findings, with some agreeing on the need for further exploration of galaxy dynamics while others contest the validity of speculative ideas without supporting references. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are limitations regarding the assumptions made about galaxy dynamics and the nature of FRBs, as well as unresolved questions about the feasibility of proposed radar applications and the need for empirical support for speculative ideas.

This appears to be a New Scientist scoop:

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.
