Figure 42: The bullet cluster 1E0657-56. The hot gas stripped from both subclusters after the collision is colored red-yellow. The green and white curves are the isocontours of the lensing convergence parameter κ (Eq. 113View Equation). The two peaks of κ do not coincide with those of the gas, which makes up most of the baryonic mass, but are skewed in the direction of the galaxies. The white bar corresponds to 200 kpc.
