Story summary

Perimeter Institute researchers developed KISS-SIDM to track the evolution of self-interacting dark matter halos that could host galaxies like the Milky Way.
The study highlights gravothermal collapse, where gravity heats a system as it loses energy, affecting halo dynamics.
The research, published in Physical Review Letters, suggests these dynamics could inform understanding of black hole formation in the final stages of collapse.
