    from one of the papers:

    (4) The ring is brighter in the south than the north. This can be explained by a combination of motion in the source and Doppler beaming. As a simple example we consider a luminous, optically thin ring rotating with speed v and an angular momentum vector inclined at a viewing angle i > 0° to the line of sight. Then the approaching side of the ring is Doppler boosted, and the receding side is Doppler dimmed, producing a surface brightness contrast of order unity if v is relativistic. The approaching side of the large-scale jet in M87 is oriented west–northwest (position angle [​IMG] in Paper VI this is called [​IMG]), or to the right and slightly up in the image. Walker et al. (2018) estimated that the angle between the approaching jet and the line of sight is 17°. If the emission is produced by a rotating ring with an angular momentum vector oriented along the jet axis, then the plasma in the south is approaching Earth and the plasma in the north is receding. This implies a clockwise circulation of the plasma in the source, as projected onto the plane of the sky.

    Doppler beaming!

    I used to have a boat we called the Black Hole because it had supergravity for any nearby $$$s. It would suck them right in, never to be seen again.

    :lol:

    I once lived in an area where the streets were named alphabetically: Edina, Geneva, Helena, Faraday (well, nearly alphabetical), Iona, Java, Kenora. We were on Kenora but we daydreamed about living on Iona so that we could dub our house ... Iona Money Pit :p

    Pretty cool image!

    Better still, it was taken via international collaboration!

    Screw the 'verse, I see hope for humanity!

    Aha!

    Looks pretty much like we thought it would.

    Black Holes are Real!

    What boggled my tiny brain was the distance they quoted:
    Three hundred million trillion miles away.
    How many zeroes is that?

    Amazing stuff. Space is cool.:cool:

    if you squint - you can almost see all the missing socks from our collective dryers falling relativistically into the event horizon

    Well, I'm with Buckocaster. I can't tell you how happy that's a BLACK HOLE. This is why I'm constantly disappointed by demonstrations in particle physics. Everything looks like fuzzy blobs and the physicists get to tell me exactly what I'm looking at.
