Spiral arms effectsΩsp=15 km/s/kpcΩsp=20 km/s/kpc•Kinematic response to <strong>the</strong> spiral arms is strong and depends on disc position•Significant changes: ~0.6 kpc in radius, ~2 kpc in azimuth•Strong effects: close to <strong>the</strong> 4:1 inner resonance•Where do we find more substructure? It depends on <strong>the</strong> pattern speedT. Antoja Sydney, 24/07/2012
