Transformation of rotating disky Fornax into a nonrotating spheroidal via tidal stirring. Top row: beginning of the simulation. Bottom row: After 6 Gyr. Left column: Surface density maps. The marked isophotes enclose 50% and 80% of the mass of the resulting object. Middle column: maps of average line-of-sight velocity. Right column: Maps of the on-sky tangential velocity. All maps are views from the center of the MW. Fornax moves to the right. The bar in the lower left panel indicates one degree on the sky.
