Top panel: hadronic and Coulomb cooling rate of CR energy inside the box for the different runs. Bottom panel: CR adiabatic losses (−P_CR∇⋅u <  0). We find that the cooling rate is higher for lower diffusion. We find that adiabatic losses are subdominant except in the isotropic and anisotropic diffusion simulations with the highest diffusion coefficients. The black dotted line corresponds to the streaming losses (−u_st ⋅ ∇P_CR) in the “Streaming Boost” simulation.
