Stellar kinematics of galaxies at redshifts around cosmic noon. Top panels: stellar velocity field (V_⋆) and velocity dispersion distribution (σ_⋆) obtained from mock HARMONI observations of three hours of on-source exposure time of lenticular (i.e. NGC 809) host galaxies scaled to the V-band luminosities indicated in each panel at redshifts 0.76 (a and b), 1.50 (c), and 2.30 (d), as also indicated. Bottom panels: same 2D-distributions but from mock HARMONI observations of six (e), nine (f and h), and 12 (g) hours of total exposure time of a lenticular hosts of the luminosities in the V band, which is labelled (i.e. 10¹¹ L_⊙ (e–g)) and 10¹⁰ L_⊙ (h). Contours (in black) from the stellar continuum are overlaid in steps of 0.25 mag. For all panels, the colour bars are in the [−150,150] km s⁻¹ and [20,200] km s⁻¹ ranges for velocities and velocity dispersions, respectively.
