Work by Cosmology Center Hubble Postdoctoral Fellow Dr. Marcel Pawlowski and collaborators has shown that the orderly motion of satellite galaxies around Centaurus A, Andromeda as well as the Milky Way are not what is expected in structure formation simulations, and may have implications for dark matter.
The study made it to the cover of Science Magazine today and was covered in the LA Times, Forbes, New Scientist, Astronomy Magazine and Sky & Telescope.
The paper is available on the arXiv.
