Cosmic robbery: New study explains how smaller galaxies lose their dark matter

Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests. 

Scientists from the University of California, Irvine and Pomona College used computer models to simulate the evolution of a corner of the universe about 60 million light-years across. The new computer models, which weren’t designed to do so, created seven galaxies deprived of dark matter, a sight that had previously puzzled scientists. The strange simulations arose after near-collisions with massive neighboring galaxies, according to a statement from the University of California, Irvine.
