One of the very exciting things about the Eagle project is that it is possible to pick out interesting objects, and then re-simulate the volume around them at higher resolution giving a much better view of what’s going on and letting us find even the smallest galaxies.
So what are the smallest galaxies? Surely galaxies can be as small as you want? Well – no. There’s a limit to the smallest size of galaxies, and Till Sawala has just written an exciting paper demonstrating why.
The science paper is available here… http://arxiv.org/abs/1406.6362
but we’ve also issued a press realease with some very cool pictures. The full pictures are here… http://star-www.dur.ac.uk/~till/
