Cloud density evolution

The following images and plot are products from a cloud-wind simulation with the following parameters:

• Resolution: 1024x384x384
• Size: 80x30x30 pc
• Wind density: \(n_{wind} = 0.1 \, \mathrm{cm}^{-3}\)
• Wind temperature: \(T_{wind} = 5 \times 10^6 \, \mathrm{K}\)
• Wind velocity: \(v_{wind} = 1200 \, \mathrm{km} \, \mathrm{s}^{-1}\)
• Average cloud density: \(n_{cloud} \approx 75 \, \mathrm{cm}^{-3}\)
• Cloud radius: 5 pc
• Cloud mass: \(\approx 800 \, \mathrm{M}_{\odot}\)

All material with a number density higher than \(n = 1.0\) is considered part of the cloud.

The following four snapshots show the evolution of the cloud over the first 400,000 years of the simulation. Snapshots are spaced 100,000 years apart.

Below is a density pdf showing all the material in the simulation. Lines correspond to the five snapshots above, with the color gradient going from darkest (snapshot 0) to lightest (snapshot 400k).
