Collage of six cluster collisions with dark matter maps
This collage shows NASA/ESA Hubble Space Telescope images of six different galaxy clusters. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. 72 large cluster collisions were studied in total.
Using visible-light images from Hubble, the team was able to map the post-collision distribution of stars and also of the dark matter (coloured in blue).
The clusters shown here are, from left to right and top to bottom: MACS J0416.1–2403, MACS J0152.5-2852, MACS J0717.5+3745, Abell 370, Abell 2744 and ZwCl 1358+62.
