I wanted to find evidence of black holes playing a torsional role on the systems inside of a galaxy in such a way that maybe there are relationships which bind the two and can explain galactic rotation curve phenomenon. The article I am about to link to, explained there are such relationships between the orbital speed of the stars on the outer rim and the size of the supermassive black holes at the center of galaxies:
I realized this could answer a problem that surfaced in cosmology not long ago: We look back 10 billion years and find that galaxies are behaving like they consist of ordinary matter. The cosmological world went abuzz and asked, ''where did the dark matter go?''
I realized this could be answered if the dark matter phenomenon was somehow linked intrinsically to the black holes at their galactic cores. The black holes would not have been supermassive 4 billion years years after big bang, or approximately 10 billion years ago, when the earliest galaxies were starting to form. And so, it seemed that this was a nice solution then to a weird problem: the reason those dark matter effects for galactic curves were not about, because their galactic core black holes were too small to account for it.
After some investigation, it seems like it may be a candidate to provide evidence of black hole torsional structure. It seems that the result of this galaxy losing its black hole could have resulted in the galaxies famous ''loose arms.'' Galaxy is called the Triangulum.
The core is surprisingly a nebula but there is more activity going on in the loose arms of the galaxy than what appears. Star formation should be happening in the center but surprisingly star formation is low.
I am reading this right now, just understanding some basics of the rotation curves of M33.
What was found was that there was nothing too peculiar about the rotation curves, but what I later found out was that there is in fact a lot of activity hiding behind the thick curtain of gas in its arms and there is black hole activity in there.
Then I found a second case to compare the theory, that black holes literally hold the structure of a spiral galaxy together in such a way, that the rotation curves will boil down to the same phenomenon.
This galaxy seems to strengthen my hypotheses about M33. This galaxy had its supermassive black hole ripped away much earlier (or is that later?) than M33. The idea its black hole has been ejected is one of the top explanations apparently. What has happened, is not a collapse of the system, but stars are now diverging away from each other, its massive bulge that is still there - that bulge is created by a gradual separation over time, it probably was never that large.
The bulge is a bit of a mystery, but it can be understood as the separation of the stars in the absence of the supermassive black hole that are now drifting apart. Likewise, M33 is such a case, albeit, an advanced one. It too is loosely separated, the arms are drifting off into space and loosing the rotational energy it once had. This galaxy we just looked at lost its black hole much earlier than M33 lost its supermassive black hole.
The theory was strengthened enough that I have made a new post about this discovery. It's not that the rotation curves disappear when the central black hole disappears, it is that the structure itself will eventually fall apart - the rotation curves seem to be present so long as there is black hole activity. The galaxy which is 10 times the size of our Milky way, will eventually loose its bulge, it will deviate further and further away, maybe fall back on the galaxy and flatten out. There is still black hole activity going on in the arms of M33 and there is black hole activity going on inside of Abel 2261 which appears to be, helplessly, holding the structures together. As in the case of M33, the arms are loose and falling away from the center, which is direct evidence the entire spiral structure owes its structure to the supermassive black hole and if not present, will be overcome by the centrifugal force of the galaxy.
