Spatial variations of the phase-space patterns in simulated galaxy at 0.76 Gyr (top row) and at 2 Gyr (bottom row). Each frame corresponds to number density (left panels), mean azimuthal (middle panels), and radial velocities (right panels) in z − νz plane for stars selected in small arcs |R − Ri|< 0.5 kpc and |ϕ − ϕi|< 7.5°, where cylindrical coordinates (Ri, ϕi) are indicated on global axes. Each frame axes size is [ − 1; 1] kpc × [−50; 50] km s−1. Total galaxy stellar surface density contours are over-plotted by black lines, which clearly show the position of the bar in galactic cylindrical coordinates. Number of particles varies from ≈4 × 106 in the innermost frames to ≈0.3 × 106 in the outermost frames.
