IMFs for the models with M_bh = 10⁸   M_⊙ and UV = 0. The images display the time-averaged IMFs between 1 and 3 free-fall times, where t_ff = 10⁵ yr. 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 to 160 erg   s^-1   cm^-2. In each image, for comparison purposes, the Salpeter IMF (green dashed) and the Chabrier IMF (blue dot-dashed) are displayed as fitted to our fiducial model. Two best fits are applied to the data, a linear fit and a lognormal fit, and are shown as purple and red lines. With the exception of the lognormal fit, the slopes above the turn-over mass are given in the upper left corner.
