My first time posting – Read some of your comments and am impressed with the depth of examination of the subjects. Still, am not confident that any of you will be sufficiently tolerant of contrarian scientific concepts to allow me to post again.
M64 is an intriguing example of a hypothesis I describe as ‘flip-flop’ or tumbled galactic nucleus.
First scientific heresy: The claim here is that the sudden, uneven loading of a black hole can cause that spinning body to wobble, e.g., our own galaxy and M31, and can in extreme cases flip or turn over, and appear to spin in a direction opposite to its earlier spin. In the example of a wobble, the extra mass forms a node on the total nuclear mass. The propagating (mostly) gravitational waves through the galaxy cause the outer most stars to form a wavy edge. In the latter case the impacting (black hole) mass is large enough to force the resulting entity to roll over. Development of the galaxy from this point on is influenced by this new rotational direction.
Second scientific heresy: Directly and indirectly the galactic nucleus, with a number of emanations (not described here), influences the star pattern (formation) of that galaxy.
Third heresy: Black holes do not or cannot completely merge, one with another. Particularly those that have spin. They may form a close, intimate association, but not a singular union. Perhaps only light seconds apart , they may exhibit other properties in common.
Thus, a mature galaxy’s nucleus may be composed thousands, perhaps billions, of black holes of all masses and spin. The changing configuration, or relationship between units, of the black hole content of the nucleus over time affects the pattern of new star formation. Every new addition of mass alters a bit the stability of the earlier association of black holes forming the nucleus. E.g., when the overall orbital pattern of the black holes to each other is random not fixed, star formation will be look random or peculiar. With additional mass the black holes will take up more or less fixed orbits. The new star pattern becomes elliptical or spherical. The emanations, such as various radiation, gravity and magnetic waves, become more orderly. With the acquisition of even more black holes, along with their mass and angular momentum, the nucleus is forced for the sake of harmony to assume an overall flattened bar shape. (There are always rogue, non conformist black holes in the environment; can cause redirection of nuclear energies.) The emanations find it convenient to travel down the bar and to discharge from the tips. Mostly. The width of the nuclear bar (our view) depends upon the number of black hole masses that lay outside that prominent line of black holes that together turn slowly like the propeller of a plane. It is the discharged energy from the tips that triggers new star formation. The galaxy now looks spiral. (The number of rogue holes determines the width of the bar, or its complete absence.) [I have written extensively on this subject.]
Getting back to M64 - This may a case of the spiraling nucleus being suddenly flipped over; it continued to produce new stars with the spiral patter, but in a different direction.
For an example if a 90 degree flip see NGC 4650A. The Hubble Heritage Project's picture.
Thanks for letting me post this one time. Too bad I won’t get to describe ‘Mitosis of Galactic Nuclei’.
