A Gamma ray burst associated with LIGO GW event

Click For Summary
The Fermi Gamma-ray Burst Monitor detected a hard gamma-ray burst approximately 0.4 seconds after the LIGO gravitational wave event, which is unexpected for a black hole merger. A new paper suggests this could be explained by the merger occurring within a star, although this theory is met with skepticism. The discussion highlights the need for caution in associating these two events, as they may be unrelated. The gravitational wave detection has a high confidence level, while the gamma-ray detection is more marginal, raising questions about their potential correlation. Overall, the findings prompt further investigation into the mechanisms behind these astrophysical phenomena.

It appears you're asking whether or not LIGO can detect the gravitational waves generated by in-spiraling massive objects. Is that correct?

No, I was asking if the geometry was sufficient, and the event was sufficiently violent enough to produce gravitational waves of sufficient amplitude to be detected by the LIGO instrumentation

So you're asking about gravitational waves? Looking at your earlier post:

No, I was asking about the geometry of gravity waves in space-time caused by any event, not just two black holes spiraling into each other, and if Δx, Δy, Δz, Δt must have sufficient amplitudes caused by such an event or events, to be detected by the LIGO instrumentation.

I'm sorry, Eimackman, but I still don't understand what you're asking and I don't know enough about GR to make an accurate guess. I think I'll just bow out of this conversation here and let someone else take over. Thanks for your time.
