Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter. The tool shows how rare dark matter interactions can heat and collapse galaxy halos, potentially explaining dense galactic cores and the early formation of supermassive black holes.Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter.
