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

[exponent137]

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?

Some new papers...

Links?

For instance, one reference is:
https://phys.org/news/2018-06-short-gamma-ray-binary-neutron-star.html
and therein.

But, maybe this delay is not explained there. Maybe this research is not focused on this delay?

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

Now I found something:

But, I see that there is no progress according to knowledge in 2017? Thus we need wait the next merger.
