Most of dwarf spheroidal galaxies in the Local Group were probably formed via environmental processes like the tidal interaction with the Milky Way.We study this process via N-body simulations of dwar...
Optimal stirring strategies for passive scalar mixing
Optimal stirring strategies passive scalar mixing

We address the challenge of optimal incompressible stirring to mix an initially inhomogeneous
distribution of passive tracers. As a quantitative measure of mixing we adopt the H1 norm of th...
