I wanted to ask what would be the best way to get an angular momentum/spin of the gas? I see there is a SubhaloSpin, but calculating spin given the gas particle columns would be challenging as it seems I would have to calculate the distance from the center of the galaxy, a peculiar velocity, etc.
If these quantities would work for you, you could get in touch with Jolanta Zjupa and check if she has re-done this analysis for TNG (I believe so).

Hey Dylan - I think that would be exactly what I need, but given the sizes of the snapshots and me wanting to look at the evolution of spin over multiple snapshots, the only real way (given storage constraints) I would probably be able to evaluate that is if it were on the JupyterLab Workspace. I'm guessing it wouldn't be added to that, right?

Supplementary datasets can be added to the Lab, if they exist, so I would suggest to ask Jolanta if these exist and/or if she would be willing to release them.

For the original Illustris we had a supplementary dataset "Halo/galaxy angular momentum and baryon content".

Will do, thanks!
