A cosmic jellyfish


Simulation I set running before I went on holiday. This one has a much higher density surrounding medium than the last one did, so the effects are much more dramatic. As with the last one, it's an otherwise stable cold, dense gas disc face-on to a 1,000 km/s wind of hot, low density gas.

Unfortunately I forgot to change the density of the wind. So, although the surrounding medium is initially much denser, as intended, it gets quickly replaced by a much lower density medium.

Interestingly, even after the medium is replaced with the uniform low-density gas, the cold gas removal seems to happen in pulses. That wasn't what I was expecting at all.

  1. Weeeell...you often get a sting in the tail with a jellyfish. (Sorry, somebody had to say it!)
