Figure 43

Figure 43: A MOND model of the bullet cluster [17]. The fitted κ-map (solid black lines) is overplotted on the convergence map of [102] (dotted red lines). The four centers of the parametrized potential used are the red stars. Also overplotted (blue dashed line) are two contours of surface density. Note slight distortions compared to the contours of κ. The green shaded region corresponds to the clustering of 2 eV neutrinos. Inset: The surface density of the gas in the model of the bullet cluster.
