Discussion Overview

The discussion revolves around the correlation between gravitational waves and multiple rebrightening gamma ray bursts (MRGRBs), particularly focusing on whether gravitational waves can be detected prior to the first peak of these bursts. Participants explore the frequency ranges of gravitational waves relevant to this inquiry and the potential involvement of organizations like the IPTA and LIGO.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant inquires about any correlations between gravitational waves and MRGRBs, specifically if gravitational waves are detected within a certain time frame before the first brightening peak.
  • Another participant notes the lack of responses to this specific question, suggesting that there may not be current knowledge on the correlation.
  • A participant mentions that LIGO's detection capabilities may not align with the frequency ranges of interest for MRGRBs, which are suggested to be in the mHz to nHz range.
  • There is a discussion about the potential of LISA to detect low-frequency gravitational waves associated with MRGRBs, with a noted delay in its launch until 2037.
  • Some participants express uncertainty regarding the frequency ranges mentioned, questioning the appropriateness of the nHz range and its implications for the time periods involved.
  • One participant shares their intent to gather evidence for a personal idea related to the topic, while another reminds them that personal research may not be suitable for the forum.

Areas of Agreement / Disagreement

Participants express uncertainty and differing views regarding the detection of gravitational waves in relation to MRGRBs. There is no consensus on whether such correlations exist or on the appropriate frequency ranges for detection.

Contextual Notes

Participants reference various gravitational wave detection projects and their capabilities, highlighting limitations in current knowledge and technology. There is an acknowledgment of the need for further evidence and exploration in this area.

TL;DR
Has anyone correlated gravity waves with multiple rebrightening gamma ray bursts where the bursts are of constant time separation?
Hi Guys. I am interested to find out if anyone at the IPTA or other relevant organizations have correlated gravity waves with multiple rebrightening gamma ray bursts where there is a constant time (t) between 3 or more rebrightening's? If so, did the detection of the gravity wave occur between 0-0.25t seconds before the first brightening peak. Example gamma ray bursts below - I added the red curves.

I am just an interested amateur and have not done any university math's since 1988 so please be kind!!

Here's a couple of older (before the IPTA started measuring) GRB's with 3 peaks for example

Thanks for the correction berkeman - I shall be more careful with my nomenclature.
It seems though that there are no takers for this very specific question. Guess no one knows at the moment ☹. Would be interesting to know if any gravitational waves do get correlated with MRGRB's and actually lead the first brightening peak (not the rumble before) by <=0.25 x the peak to peak separation.

The only way to do this would be if there was a LIGO detection corresponding to these events. At least with a quick web search, it does not appear that that was the case.
 
Hi Peter
Thanks for the reply. I have looked at LIGO but the frequency range of 1-1000Hz is too high.
(Black hole mergers an example). The waves I am looking at would be in the mHz to nHz range - see pic below

LISA is the best bet to pick up gravitational waves of the mHz range (if any are associated with MRGRB's).

It hasn't been been launched yet - 2037 planned launch! Ill be old then!!

I'm hoping the IPTA has picked up low frequency waves that look like below. X axis is time. Y axis would be flight time of pulses from pulsars relative to c. Looks totally different to LIGO black hole merger waves. Would be nice to know if this type of gravitational wave exists.

Based on what?

Nanohertz means a period of decades. Are you sure that's what you mean?
 
Hi Guys
Thanks for the responses - been a bit busy.
@PeterDonis - I'm trying to gather evidence for an Idea I have. No good talking about it until I have something to go on - would be a bit foolish as I am just a layman when it comes to Cosmology. It's probably wrong but you never know. Lets see if those waves exist first. Any help with finding if these exist would be gratefully received :)

@Vanadium 50 - If you look at the chart above of the frequency ranges of gravitational waves, the stochastic background is around -nano Hz (you need the IPTA to detect these - https://ipta4gw.org/). The wavelength of MRGRB's would be in the milli Hz range. So there may be waves anywhere in the range of milli to nano Hz. We are talking about space so decades may be plausible?
Thanks for your interest and helpful comments guys.

Personal research is off topic for discussion here.
