Fig. 9

Average radial profiles of the disks for different strengths of internal UV fields and dust-to-gas ratios at z = 5.4. The left panel of this figure shows radial profiles for disk 1 and right panels shows the radial profiles for disk 2. The top two panels show the ratio of rotational to orbital velocity for the disks. The Toomre parameter Q for each disk is depicted in the bottom panels. The value of an escape fraction for ionizing radiation is 10% for both panels.
