SO, THE MULTI MILLION DOLLAR QUESTION:
IS THERE GAS ACCRETION INTO THE BLACK HOLE? OR NOT?
The blue part of the cool Hydrogen disc is approaching us. The red part ( left) is receding. Just like the ring disc around M87!!
However there is also a kind of tail.( right down-side) which can hardly be the jet.
The distance to the event horizon seems to be large ! 20.000 x the diameter of the event horizon.
Which is in line with Q-FFF Theory, which says, that Black holes do not eat Fermionic matter, but make accelerated jets out of it.
So it is not clear that the gas is flowing into the black hole !!

“We are also probing accretion onto the black hole. "
"Even so, we still have no good understanding of how its accretion works.
We hope these new ALMA observations will help the black hole give up some of its secrets."

As a consequence, we may expect that the gas cloud called G2 desintegrated in 2014 ( see below) is eaten by the black hole, but absorbed into the cool or even hot the larger gas disc which is now observed. see: https://www.astroblogs.nl/2015/03/26/beste-waarneming-tot-nu-toe-van-stoffige-wolk-g2-die-zwart-gat-galactisch-centrum-passeert/
