Dwarf Galaxy with SPH

This animation by David Williamson, Hugo Martel and Daisuke Kawata shows a single frame of a dwarf galaxy simulated with the SPH code GCD+ (written by Daisuke Kawata). The visualization was generated by calculating the column density of the gas through the simulation volume in a given direction using the SPH smoothing kernel and then plotting the resulting 2D image. This projected view reveals the shape and structure of low-density bubbles. These are less visible in a simple scatter plot of particle densities.
