Galactic fountain cloud going through the Galactic corona: download mov
In this hydrodynamical simulation (with the code Athena, Stone et al. 2008, ApJS, 178, 137) a fountain cloud leaves the disk of the Milky Way at 75 km/s, launched at a low angle. The cloud has a temperature of 10^4 K and Solar metallicity, the corona has T=10^6 K and Z=0.1 Solar, the two media are initially in pressure equilibrium. At the end of the simulation the mass of cold gas (T<3x10^4 K) has increased by 20% (Marinacci et al. 2010, Armillotta et al. in preparation).

Galactic fountain in the Milky Way: download mp4, download mov
This movie shows the comparison between the HI emission observations of the LAB survey and the predictions of three models: 1) thin disk, 2) simple galactic fountain and 3) galactic fountain with gas accretion.
