Table B.1
Initial conditions for the full galaxy simulations, with Npart being the resolution in number of particles, Hi the scale height, σi the initial velocity dispersion at a scale of 0.1Hi (when relevant), Ti the initial temperature, and Qmin the minimal value for the Toomre parameter. The gas particles are then used to generate the initial gas density, and the other are used directly.
