Link between dark matter and baryonic matter

Hello!

I just read the work: https://arxiv.org/pdf/1609.05917v1.pdf
The authors conclusion: "The dark and baryonic mass are strongly coupled."

Only now they have noticed this?

8 years ago I came to the same conclusion. One can even read this ratio directly from rotation curves: they oscillate. Now, the authors speculate what may be the cause. And I have the explanation already ready

"The dark matter is to be concentrated in the spiral arms. This contradicts the assumption that it consists from particles that surround the galaxy like a halo. On the other hand, this is strongly reminiscent of the asteroid belt in our solar system or rings around Saturn and Jupiter. Therefore, it may act on dark matter around small cosmic bodies, such as rocks, asteroids, planets, comets, and snowballs. They are small to be seen from a distance, but in principle they can make up the bulk of our galaxy and other galaxies."
