IMF varies with distance from the black hole Star formation suppressed r < 0.02pc "Top-heavy" IMF* for r < 0.5 PC * Details are sensitive to the accretion sub-grid model Plot of Number dN_s/d ln M_s vs Mass M_s (M_sun), showing the distribution of stars at stellar masses ranging from 10^-2 to 10^2 solar masses. Lines plot the distribution at various distances from the central black hole. At r<0.02, there are fewer stars overall. At 0.05 < r <0.5, there are more massive stars than the usually IMF distribution.

By combining FIRE + STARFORGE codes, you can simulate star formation on galaxy scales, and then zoom all the way in to individual stars. It's super cool.
This way you can do things like check if the IMF changes with galactic distance. It seems like very close to the central black hole (within 0.5 pc), you might preferentially form massive stars.
