Title: Dwarfs in the Milky Way Halo Outer Rim: interaction with the Milky Way
Preface: We study the secular evolution of gas rich dwarfs that interact with the Milky Way hot halo
through ram pressure and KH stripping.
For this we implemented wind tunnel models, setting up multicomponent models in equillibrium with DICE
for a dwarf galaxy, containing a stellar component (Plummer), a gas component (also Plummer), and a dark matter component (Burkert halo).
Then we run the hydrosimulations with the grid code Ramses, which is well suited for modelling the discontinouities like shocks.
The wind is injected with a gas density and temperature according to observational models of the MW corona.
For now we assume here that the hot halo is static (some observations might indicate some coronal flow)
and the galactic wind is given by the relative motion of the dwarf in the medium.
Here we explore a velocity wind of 200km/s (many more values to be tested).
