This shows a visualization I created of the gas distribution in one of the AREPO 20 Mpc no-feedback cosmological simulations. Both the color and the intensity reflect the total projected gas surface density. A host of gas rich disks can be seen in the haloes that our camera focuses on, as well as in along the background cosmic web. We gave it a fun soundtrack; Turn up the volume and enjoy!

This visualization I created shows nested views of the gas distribution from the GADGET/AREPO comparison project. The top panels show the gas distribution in AREPO, while the bottom panels show the same volume rendered from the GADGET simulation. One of the main points from this visualization is that the gas distribution is very different on small (galactic) scales, where we found abundant artificial clumps in the GADGET calculation.

I created this visualization from simulations that I ran with Dave Patton to identify the origin of star formation rate enhancements seen at large separations in SDSS. We found that if we sampled merger orbital parameter space, then we easily could produce galaxy pairs with enhanced star formation rates at large(!) relative separations.
