Distributions of number density n, temperature T, and turbulent plasma beta β_tur in the multiphase ISM simulation. Shown is a two-dimensional slice from the 2048³ simulation, displaying the number density (top), temperature (middle), and turbulent plasma beta β_tur = ρv²/(B²/8π) (bottom), where ρ is the gas mass density and v is the local turbulent velocity. For visualization purposes, only half of each slice is shown. The CNM, characterized by low temperature, is spatially correlated with the densest regions.
