SFEs for the models with UV. The UV flux used in these models is 10^2.5   G₀. Similar to the figures above, Figs. 10 to 12, the images show the ratio of the total sink particle mass over the total initial gas mass and is plotted against time (in free-fall units). From left to right, the cosmic ray rate increases from 1, 100 to 3000  ×    Galactic. From top to bottom, the X-ray flux increases from 0, 5.1, 28 to 160 erg   s^-1   cm^-2. These UV models are simulated for a a black hole mass of M_bh = 10⁷   M_⊙. The total number of sink particles formed during the run is given in the upper left corner of each panel.
