Astronomers offer possible explanation for elusive dark-matter-free galaxies
UC Riverside-led study finds extreme tidal mass loss in dwarf galaxies formed in a simulation Author: Iqbal Pittalwala Share This: A team led by astronomers at the University of California, Riverside, has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past. Galaxies that appear to have little to no dark matter — nonluminous material thought to constitute 85% of matter in the universe — complicate astronomers’ understanding of the universe’s dark matter content.
