Following up on the GRG18 news, the LIGO collaboration have posted a paper on the non-observation of gravitational waves from the bright electromagnetic event GRB 070201. Of course, this has been reported in a number of places already.

Thanks for the follow-up.
Interesting to see whether dark gravitons with large Planck constant could demonstrate their existence as absence of the signatures for ordinary gravitons. Radiation would be organized into lumps of much larger power than expected for steady flow and would be interpreted as noise.
By the way, these quivers at 2-surface bring to my mind the decomposition of partonic 2-surface to independent conformal patches bounded by a net of curves: each patch is analogous mountain with top identified as Higgs expectation maximum and the curve binding given mountain corresponds to saddle curve. I my guess that only the topology of quiver matters then there might be a connection.
Hi Kea,
that is a peculiar picture of M31-M110. Where did you get it ? It seems to have been taken on some UV wavelength or something like that.
Cheers, and merry xmas!

It's from the linked paper, Tommaso.
