A visualization of a simulated Coma galaxy cluster analog, showing gas surface density in pink and magenta, shock dissipation in cyan and green, and velocity field streamlines in white overlaid on the main image. Two dashed circles mark the cluster radii R200c and R500c. Inset panels show the brightest cluster galaxy's stellar surface density (upper right) and comparisons of simulated Compton-y and X-ray surface brightness profiles against Planck and eROSITA observations (lower left and lower right). — Simulated Coma Cluster Analog from Manticore-Constrained Initial Conditions
