I mentioned previously that I have been working on a galaxy simulation with a star forming region in the center. Things have been progressing, I think I can go to running 3D simulations sometime in the next two months. I will share more information when I have it, but I just wanted to share a cool picture that I made from my simulation.
This is a density map of the r and z directions (x and y, on this image) of a galaxy, or a slice in the x-z plane at y=0 if you prefer. So top and bottom of the image correspond to above and below the galaxy. We are looking at the galactic disk edge on.There are a few cool things about this image that made me excited, mostly the long filaments coming out of the galaxy. I was excited about this because that is almost exactly what we see in real galaxies, and is exactly what we are trying to find through simulations. The one problem I had here is I messed up with a certain parameter which made the galaxy not be in hydro-static equilibrium to start out, which means it kind of collapsed in on itself. That explains why the disk is so narrow and so dense.
[Update]
I failed to mention that this image was rendered in ParaView. I also have a few movies that I made relating to this simulation (again rendered in ParaView). A movie showing density can be found here (Note: It is large, 27 MB). Another showing speed (magnitude of velocity) can be found here (also large, 33 MB).
