Gas temperature as a function of tidal field strength, ∣λ ₁∣, for different components of the cosmic web (and halos) at z = 0. Both temperature and tidal field are evaluated on grids. For each component, the contours enclose 10%, 45%, 80% of all the gas mass, respectively. Note that the results for individual components of the cosmic web do not include gas in halos, and that the halo gas shown here does not include gas particles in galaxies. The two dashed lines show two power-law functions with different slopes, as indicated, and the solid line shows the median temperature as a function of the tidal strength for all the gas particles.
