Rendering of the gas density in a second-generation star-forming region (dx.doi.org/10.1088/2041-8205/790/2/L35).
The simulations were done with different abundances of heavy elements, from 0.01 to 0.0001 times the solar value, here shown for 0.001 (Z = -3). They made use of a detailed chemical network including primordial species as well as C, C+, O, O+, Si, Si+, and Si2+ following the formation of carbon-enhanced metal poor stars, which was implemented with the KROME package (kromepackage.org).

Shown is a walk-through from the cosmological large-scale structure down to smaller scales into the star-forming environment.
The simulation runs were done with the Enzo code (enzo-project.org), the rendering was animated with the yt toolkit for astrophysical data (yt-project.org).

Contributing scientists were S. Bovino, T. Grassi, D. R. G. Schleicher and M. A. Latif.
The video was edited by T. Lichtenberg.
