Hot population•Some groupspersist at low |Z|below the plane:Hercules, γLeo•Hercules seen for hotvertical orbits!T. Antoja Sydney, 24/07/2012
ConclusionsOBSERVATIONS vs DYNAMICAL MODELS✦The models predict kinematic substructure beyond the local volume✦We have detected it for the first time with RAVE✦Most of the main local kinematic groups can still be detected at ~1 kpc distance✦Large-scale features + age dispersionfavour dynamical origin✦The groups shift in the velocity plane for distant samples, as expected✦Scales of variation of the groups are roughly consistent with models✦Hercules trend of azimuthal velocity with radius is consistent with effects of the2:1 OLR✦We have used the magnitude and direction of the shift of Hercules to constrainthe pattern speed of the barFUTURE WORK✦Explore the vertical variation of the groups with models✦Use shifts of other groups to constrain more properties of the bar or the spiralarmsT.
