Influence of thermal conduction is shown at regions with suficciently steep temperature gradients (L = 32 Mpc). The gray lines show the results of the corresponding simulations without thermal conduction. Panel A) and B): the density and temperature profiles at the outer shock fronts are shifted with respect to the case without heat conduction. The high-temperature region is extended outwards. The density is increased but over a lower volume (the density shock is shifted inwards). Panel C) and D): heat conduction leads to a smaller core.
