Dark matter in two galaxies simulated on a computer

Caption

Dark matter in two galaxies simulated on a computer. The only difference between them is the nature of dark matter. Without collisions on the left and with collisions on the right. The work suggests that dark matter in real galaxies looks more like the image on the right, less clumpy and more diffuse than the one on the left. The circle marks the end of the galaxy.
