Evolution of a simulated galaxy with explicit modeling of radiative transfer and subgrid turbulence. The panels from left to right:
1. gas density; brighter color indicates higher density
2. ultraviolet radiation field; brighter color indicates stronger field
3. gas temperature; blue is cold (less than 1000 K), red is hot (higher than 100000 K)
4. small-scale turbulent velocity; blue is few km/s, orange-yellow is more than 10 km/s
This is an animated version of Figure 1 from Semenov et al. 2021 (ApJ 918 13 | arXiv:2103.13406 | ADS). The animation shows the evolution of the simulated galaxy over ~200 million years (the time is shown in the upper left corner). The panels show midplane slices of gas density, temperature, subgrid turbulent velocity, and the strength of interstellar ultraviolet radiation field (in Draine units).
