Radial transport through the disk for different gas temperature thresholds. The left panel shows the mass-weighted histogram for the disk gas temperatures for VELA 7 at z = 1.5. The brown, dashed line indicates T = 1.5 × 10⁴K, the threshold used to define the cold phase, and the cumulative mass in the cold phase is around 88% of the total gas mass in the disk. In the right panel, we plot V_r/V_rot as a function of r (in units of R_d) for three different gas temperature cuts, as labeled. There is no significant additional contribution to average radial velocities through the disk from gas above T = 1.5 × 10⁴K.
