Face-on view of Milky Way galaxy simulation - with & without stellar feedback

The gas density of a disc galaxy, modelled to be like the Milky Way (in terms of mass and size) at a low gas fraction (10%), which is equivalent to the Milky Way today. The two videos are identical except that the left galaxy has no stellar feedback. The galaxy without stellar feedback can be seen to clump up significantly more. These were produced as part of my Masters thesis, which can be found here: https://lup.lub.lu.se/student-papers/...
