The evolution of the σ-mass relation with redshift. Left: dynamical masses. Right: stellar masses. Colors and symbols as in Fig. 17. The numbers give the average redshift in each bin. The full lines show the best-fit relation σ = σ_C(M/M_C)^0.23 with uniform galaxy weighting, the dashed line with selection weighting. The blue lines show the reference line at zero redshifts. The vertical line indicates the M_C = 2 × 10¹¹   M_⊙ mass.
