Dark atoms and molecules could perhaps clump together
into galactic disks that overlap with the ordinary matter disks and spiral arms of galaxies such as Andromeda.

In the simulations, described in a study published in the September 15 issue of Nature, Sagittarius stirred up enough ripples to make a smooth, circular, spinning
galactic disk evolve
into a spiral much like the Milky Way.
The gas in the
galactic disk will circulate faster and faster as it spirals
into the vicinity of the SMBH.
The Milky Way galaxy is at least 50 percent larger than is commonly estimated, according to new findings that reveal that the
galactic disk is contoured
into several concentric ripples.
The «Local Bubble» of low - density, hot and ionized gas, is actually part of a tube - like chimney that extends through the local region of the spiral
disk into the surrounding
galactic halo, and so may can act as a vent for the energetic hot gas produced by supernovae (more).
Active vents seen in other galaxies have been called «
galactic fountains» while the gas falling back
into the
disk have been dubbed «
galactic rain.»
The local void of gas extends out of the
galactic disk and stretches
into the overlying
galactic halo region.
