A number of pictures and some animations similar to the ones below have had much press recently. Clearly the colours are artificial, but I wondered how accurately the represent the geometry of the system -- the relative sizes of the event horizon and the thin and thick accretion disks, the distance from the companion star, and so on.

Does anyone know. enter image description here

The images are taken from popular press sites, but seem to originate from ICRAR, where they are described as "artists impressions". I would nevertheless be interested to know how accurate a brief their artists were working from.

  • $\begingroup$ Post sources. Otherwise no one can help you. Possibly this visualisation is the outcome of a MHD simulation, and would then represent the real system geometry, but without a source noone can say. $\endgroup$ – AtmosphericPrisonEscape May 1 '19 at 14:39
  • $\begingroup$ @AtmosphericPrisonEscape Source added as far back as I can trace. $\endgroup$ – Steve Linton May 1 '19 at 14:45
  • $\begingroup$ The publication this article is about is an observation about the jets changing direction. So probably, as the image captions say on this website, those are just artists impressions. $\endgroup$ – AtmosphericPrisonEscape May 1 '19 at 15:33
  • $\begingroup$ @AtmosphericPrisonEscape Sure. But someone on here might know more from other sources. $\endgroup$ – Steve Linton May 1 '19 at 15:35
  • $\begingroup$ I guess it would depend on what degree of accuracy would be acceptable, but as these are for illustrative purposes only I think it would be fair to say they are not very accurate at all. $\endgroup$ – bushell May 1 '19 at 16:09
