The name “Eris” for a galaxy simulation has always made me think of that animated movie Sinbad, and this one scene where the goddess Eris is “bathing” in a spiral galaxy. Anybody else? Just me? Okay.

Density profiles for the center regions of four galaxy simulations. The location of maximum dark matter density is marked by a filled circle. The Eris simulation (blue curve) has its dark matter peak offset much further from the dynamical center than the other three simulations.
