## QED III

QED is suite of simulations follow supernova-driven outflows in varying galactic environment. The simulations follow outflows from a $1$ kpc$^2$ patch of galaxy upto a vertical height of $\sim$ few kpc in three galactic environments - Solar neighbourhood, inner and outer galaxy.
QED is a suite of simulations following supernova-driven outflows in varying galactic environments. The simulations follow outflows from a $1$ kpc$^2$ patch of galaxy up to a vertical height of $\sim$ few kpc in three galactic environments: Solar neighbourhood, inner, and outer galaxy.

### Solar Neighbourhood

### Solar Neighbourhood
The initial gas density and temperature profiles are derived using Solar neighbourhood gas surface density, $13 M_{\odot}$ pc$^{-2}$. The SN rate is $6\times 10^{-5}$ yr$^{-1}$ and the gas cools with Solar (top) and sub-Solar (bottom) metallicity. Though box height ($8$ kpc) and the resolution ($2$ pc, uniform) are the same for both the metallicities, the nature of outflows in these two cases is qutie different.

### Inner Galaxy

The initial gas surface density is $50 M_{\odot}$ pc$^{-2}$ and the SN-rate is commensurately higher, $3\times 10^{-4}$ yr$^{-1}$. The domain size and resolution are identical to the Solar neighbourhood case but note how the evolution for gas cooling at Solar (top) and sub-Solar (bottom) metallicities are closer in nature than the for the Solar neighbourhood case.

### Outer Galaxy

The intial gas surface density for these runs is $2.5 M_{\odot}$ pc$^{-2}$ for the Outer galaxy cases. Because the inital gas surface density is lower, the gas scale height of the warm phase is much larger. To accomodate the larger gas scale height the box size is increased to $16$ kpc in the vertical direction. The SNe go off in a realitvely high density surrouding medium arresting development of large scale outflows. The mass loading factor is small.

The SNe go off in a relatively high density surrounding medium arresting development of large scale outflows. The mass loading factor is small.
