Time series for the total warm (10⁴ K < T < 10⁶ K) and cold (T < 10⁴ K) gas mass for different CR transport mechanisms in comparison to the range covered by all full-physics simulations based on CRc_dsh presented in Appendix B (grey area). The dotted grey line denotes the mean of the grey area at each point in time. Overall trends are difficult to differentiate when individual simulations are compared due to the chaotic nature of cooling flows.
