Dark matter in dwarf galaxies

Now we find that the dark matter in dwarf galaxies aound the Milky Way seem to have distributions inconsistent with dark matter being cold. Cold dark matter,
if it doesn't interact with normal matter much, would tend to cluster near the center of a star cluster. OK, maybe not cluster as much as the normal matter does, but you don't expect a uniform distribution.

I didn't read the paper, and would have to read several to make sure I understood the details well enough. So I'm going by what the reporters at Space say. But...

"Either normal matter affects dark matter more than scientists thought, or it isn't cold and slow-moving, the researchers said.

Or the dwarf galaxies get churned up from time to time, and the relaxation time for normal matter is shorter than for dark matter.

So far we know very little about dark matter, including how many different kinds there are or how it interacts with itself. It might prove to have interactions as complicated as normal matter, with its atoms and molecules and structures.
