Phase spiral in the solar neighbourhood with Gaia DR3 data. Left: two-dimensional histogram of the vertical projection of phase space (Z–V_Z) from the sample of stars with Galactocentric radii of R_⊙ ± 0.1 kpc and ϕ = 0 ± 20deg. We used bins of ΔZ = 0.02 kpc and ΔV_Z = 1 km s⁻¹. Middle: same projection but colour coded according to median radial velocity V_R. Right: same projection but colour-coded according to median azimuthal velocity V_ϕ, adjusting the colour bar limits so as to maximise the appearance of the spiral.
