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 − ν_z plane for stars selected in small arcs |R − R_i|< 0.5 kpc and |ϕ − ϕ_i|< 7.5°, where cylindrical coordinates (R_i, ϕ_i) 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.
