2 second delay at the merger of two neutron stars in August 2017

Click For Summary

Discussion Overview

The discussion centers around the observed 2-second delay between gamma-ray bursts and gravitational waves during the merger of two neutron stars in August 2017. Participants explore potential explanations for this phenomenon, referencing recent papers and existing literature.

Discussion Character

  • Exploratory, Debate/contested, Technical explanation

Main Points Raised

  • Some participants mention new papers that have emerged regarding the neutron star collision and the associated delay.
  • One participant requests links to the papers discussing the delay.
  • Another participant provides a link to a reference but questions whether it adequately addresses the delay.
  • A possible explanation proposed is that gamma rays may be slowed down by passing through debris from the merger.
  • One participant shares a link to an article discussing the delay but expresses skepticism about the progress made in understanding it since 2017.
  • There is a suggestion that further observations from future neutron star mergers may be necessary to gain more insights.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the explanation for the 2-second delay, and multiple competing views and uncertainties remain regarding the mechanisms involved.

Contextual Notes

Some limitations include the potential lack of focus on the delay in the referenced research and the unresolved nature of the explanations provided.

Some new papers appeared about processes in the collision of the two neutron stars, measured in August 2017.

Is now more clear, why 2 second delay between gamma rays and gravitational waves happens?

Possible explanation - gamma rays are slowed down by passing through the debris of the merger.
