“Lucky Find” by Astrophysicists Explains How Galaxies Can Exist Without Dark Matter

In simulations, collisions cause smaller star groupings to lose material.

In a new Nature Astronomy study, an international team led by astrophysicists from the University of California, Irvine, and Pomona College report how, when tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter — matter that we can’t see directly, but which…
